Basic Characteristics of Mineral Resources – Heijingang Report
Effectiveness

The effectiveness of mineral resources is their fundamental attribute, enabling them to play a critical role in the process of human societal development. It means that these resources possess intrinsic value, capable of generating both social and economic benefits, and serve as an indispensable material foundation for human civilization. From the ancient Stone Age, when humans first began crafting tools from stone, igniting the dawn of civilization, to today’s modern industrial era—where diverse metallic and non-metallic minerals underpin vast and complex industrial systems—mineral resources have consistently been at the forefront, driving societal progress in profound and pivotal ways.
Take iron ore as an example—it occupies a central position in the steel industry. In modern society, steel is widely used across numerous sectors, including construction, machinery manufacturing, the automotive industry, and shipbuilding. In the construction industry, high-strength steel is essential for building the structural frameworks of large-scale buildings. For instance, iconic structures like New York’s Empire State Building and Shanghai’s Shanghai Tower rely heavily on steel to maintain their robustness, ensuring stability and safety even under challenging environmental conditions. In machinery manufacturing, steel components—from the intricate parts of precision watches to massive industrial machine tools—play a crucial role in guaranteeing equipment reliability and accuracy. Meanwhile, in the automotive industry, steel is extensively employed in car bodies and engine parts, directly influencing vehicle performance and safety. In shipbuilding, steel forms the backbone of hull structures and propulsion systems, determining the vessel’s seaworthiness and durability. According to statistics, global annual steel production amounts to billions of tons, with approximately 1.6 tons of iron ore required to produce just one ton of steel. This clearly underscores the immense demand and critical importance of iron ore in industrial production.
Now, let’s look at graphite ore, which also holds unique value in industrial production. Graphite boasts excellent conductivity, thermal conductivity, and lubricity, along with high chemical stability. In the electronics industry, it is an ideal material for manufacturing conductive components such as electrodes and brushes. Compared to other conductive materials, graphite offers stable electrical performance and can maintain superior functionality even under harsh conditions like high temperatures, ensuring the reliable operation of electronic devices. In the chemical industry, graphite is used to produce corrosion-resistant equipment parts, extending the lifespan of machinery and reducing production costs. Meanwhile, in the emerging field of new energy, graphite ore serves as a crucial negative electrode material for lithium-ion batteries, providing strong support for the development of electric vehicles and energy storage systems. As the new energy sector rapidly expands, the demand for graphite ore continues to rise steadily.
These examples clearly demonstrate that the effectiveness of mineral resources has made them the cornerstone of modern industry, underpinning critical sectors such as energy supply and industrial manufacturing—and playing an irreplaceable role in driving social development and economic growth.
Limited and Non-renewable
The limited and non-renewable nature of mineral resources is their key distinguishing feature compared to other resources—and an essential attribute that humanity must always keep in mind as we explore and utilize these vital assets. The "limited" aspect refers to the fact that Earth's mineral resources are finite in quantity, far from being inexhaustible or endlessly replenishable. Meanwhile, the "non-renewable" characteristic underscores that these resources were formed over vast stretches of geological time through intricate physical, chemical, and biological processes—processes that typically take millions, or even hundreds of millions, of years to complete. Once extracted and used, they cannot be naturally regenerated within the relatively short span of human history.

Taking oil resources as an example, they are often referred to as the "lifeblood" of modern industry, playing a crucial role in numerous key sectors such as transportation, energy production, and chemical raw materials. According to the "BP Statistical Review of World Energy," published by BP, as of the end of 2023, the world's proven oil reserves stood at approximately 173.26 billion barrels. While this figure may seem substantial, global oil consumption continues to rise steadily alongside ongoing economic growth. In 2023, the world consumed an average of about 100 million barrels of oil per day. At this rate, even without accounting for future demand growth, the existing oil reserves would last only around 47 years. Moreover, as oil extraction becomes increasingly challenging, the associated costs continue to climb, with some marginal oil fields now facing dual technical and economic hurdles in their development.
Looking at coal resources again, they are equally important as both an energy mineral and an industrial raw material. Globally, coal reserves are unevenly distributed, with major concentrations found in countries such as the United States, Russia, and China. However, long-term, large-scale mining has left some regions facing the daunting challenge of resource depletion. In China, traditional coal-producing areas like Shanxi and Heilongjiang have experienced years of intensive extraction, leading to a gradual decline in coal reserves, ever-deepening mining operations, and sharply rising extraction costs. At the same time, these activities have triggered a range of environmental issues, including ground subsidence and water resource degradation. According to relevant studies, if global coal consumption continues at its current pace, within the next few decades, coal resources in certain regions may no longer be sufficient to meet demand, putting severe pressure on the global coal market.
Additionally, several rare metal minerals—such as indium, gallium, and germanium—play an indispensable role in cutting-edge high-tech fields like information electronics, new energy, and aerospace. These rare metals are extremely limited in reserve and are concentrated in just a few regions worldwide. As technology continues to advance rapidly, the demand for these rare metals is experiencing explosive growth. However, given their non-renewable nature, once these resources are depleted, the development of related industries will face severe constraints, potentially even triggering technological bottlenecks and industry disruptions.
The finite, non-renewable nature of mineral resources hangs like the legendary Sword of Damocles, constantly reminding humanity: we must cherish every precious resource, abandon practices of overexploitation and waste, and pursue resource development and utilization in a scientific, rational, and sustainable manner. This is not only a responsibility to the current generation but also a crucial step toward laying a solid foundation for the survival and prosperity of future generations.
Uneven spatiotemporal distribution
The spatial and temporal uneven distribution of mineral resources is another prominent feature, profoundly influencing the global pattern of resource development and economic growth. From a spatial perspective, there are significant disparities in both the reserves and types of mineral resources across different countries and regions. For instance, the Middle East is globally renowned for its abundant oil and natural gas resources. The region accounts for approximately 48% of the world’s proven oil reserves. Countries like Saudi Arabia and Iran, benefiting from their得天独厚的优势, hold a pivotal position in the global energy market. Saudi Arabia, in particular, boasts several world-class mega-oil fields, such as the Ghawar Field, which holds an estimated 112 billion barrels of crude oil—making it the largest onshore oil field in the world. This vast reserve has generated immense revenue from oil exports, fueling rapid economic expansion and enabling Saudi Arabia to wield considerable influence on the international energy policy stage.
Australia is famously known as the "nation sitting on a mine cart," thanks to its abundant and diverse mineral resources. The country ranks among the world's top producers of iron ore, bauxite, coal, and other key minerals. Australia's iron ore, renowned for its high quality and large-scale production, is highly competitive in the global market. In fact, Australia accounts for a significant share of the world's iron ore exports, with major destinations including China, Japan, and South Korea. These exports play a crucial role in supporting the steel industries of these Asian nations, while also driving substantial economic growth and job creation within Australia itself.
Looking once again at the Democratic Republic of Congo in Africa, it is a major global producer of cobalt, holding about 50% of the world’s total cobalt reserves. As a critical and rare metal, cobalt plays an indispensable role in advanced technology fields such as lithium-ion batteries and aerospace industries. The development of Congo's cobalt resources is not only vital for the country’s economic growth but also profoundly influences the global transition toward renewable energy. Thanks to its abundant cobalt deposits, the region has attracted significant investment and collaboration from numerous international mining companies, spurring local mining industry expansion. However, this surge in resource exploitation has simultaneously given rise to a host of complex challenges—ranging from environmental concerns and sustainable development to equitable distribution of benefits among stakeholders.
In the temporal dimension, the discovery and extraction of mineral resources in the same region have also undergone significant changes over time. Take oil development in the United States as an example: In its early days, U.S. oil production was primarily concentrated in states like Pennsylvania. However, with continuous advancements in exploration technologies and deeper geological research, substantial oil reserves were subsequently discovered in regions such as Texas and Alaska, transforming them into new oil-production hubs. At the beginning of the 20th century, Pennsylvania once accounted for a sizable share of domestic oil output in the U.S. Yet as oil fields in that region gradually aged and production declined, Texas—with its abundant reserves and large-scale field-development efforts—eventually emerged as the nation’s core oil-producing area. Today, thanks to ongoing innovations in exploration techniques and extraction methods, the U.S. has achieved major breakthroughs in the shale oil sector, dramatically boosting its overall oil output. As a result, the country has even begun exporting some of its oil, fundamentally reshaping the global oil market supply dynamics.
The uneven spatial and temporal distribution of mineral resources poses significant challenges to resource extraction and economic development. For countries and regions lacking in natural resources, meeting the demands of economic growth often requires reliance on imports, which not only increases the costs of acquiring resources and heightens transportation risks but also exposes them to potential constraints from resource-supplying nations in the global market. This could lead to disruptions in resource supplies, ultimately jeopardizing the stable growth of their economies. Take Japan as an example: due to its severe scarcity of domestic mineral resources, the country depends almost entirely on imports for essential minerals such as oil and iron ore. During the two major oil crises of the 1970s, Japan’s economy suffered a severe blow—industrial production plummeted, inflation surged, and economic growth came to a standstill.
For regions rich in resources, over-reliance on the development of a single mineral resource can lead to a monotonous industrial structure and undermine the sustainability of economic growth. Once resource prices experience significant fluctuations or the resources themselves begin to dwindle, local economies will face severe challenges. For instance, several Middle Eastern countries heavily dependent on oil extraction have amassed substantial wealth during periods of oil prosperity. However, due to their economy being overly tied to the petroleum industry, they now struggle with sluggish growth whenever global oil prices decline or oil reserves gradually deplete. As a result, these nations are confronted with the urgent task of transforming their industries and pursuing economic diversification. Meanwhile, resource exploitation often triggers a host of environmental issues and social conflicts, such as land degradation, environmental pollution, and unequal distribution of resource-related benefits—further jeopardizing the region's long-term sustainable development.
The spatial and temporal uneven distribution of mineral resources is a complex yet critical characteristic that profoundly influences global resource development strategies, international trade patterns, and the economic development models and sustainability processes of nations and regions.
Invest in high risk
Investing in the mining sector inherently involves a high level of risk—an unavoidable characteristic that permeates the entire lifecycle of mineral resource development, presenting investors with significant challenges and tests. This heightened risk stems from several key factors, with the most critical being the uncertainty surrounding exploration outcomes and the volatile fluctuations in market prices.
During the mineral exploration phase, due to the extreme complexity of geological conditions and the limitations of existing exploration technologies, even after extensive preliminary geological surveys, significant uncertainties still remain regarding the actual reserves and quality of the minerals. A seemingly promising exploration area might, upon further investigation, reveal that the actual resource volume is far lower than expected—or worse yet, that no ore bodies with commercial mining value exist at all. For instance, a small mining company once conducted gold exploration in a certain region of South America. Initial geological studies and preliminary surveys indicated that the area held substantial gold potential, prompting the company to invest heavily in subsequent exploration and preparatory development work. However, as the exploration deepened, it became clear that the gold deposits were highly dispersed, with low-grade ore and prohibitively high extraction costs—making profitable mining simply unviable. In the end, not only did the company lose its massive investment in exploration, but it also found itself on the brink of bankruptcy due to mounting debts.
Market price fluctuations also pose significant risks to mining investments. Mineral prices are influenced by a complex interplay of factors, including global economic conditions, supply-demand dynamics, geopolitical developments, and currency exchange rate changes—resulting in frequent and substantial price swings. Take the crude oil market as an example: at the beginning of 2020, the global economy came to a near standstill due to the widespread outbreak of COVID-19, leading to a sharp decline in oil demand and a dramatic plunge in international crude oil prices. Notably, the May futures price for West Texas Intermediate (WTI) crude oil even briefly dipped into negative territory, hitting an all-time low. This historic price collapse dealt a severe blow to many oil-producing companies, leaving numerous high-cost shale oil projects facing massive losses. In fact, some smaller oil firms were forced to file for bankruptcy protection amid these financial challenges.
Looking at the gold market, gold—as a crucial precious metal—is influenced not only by economic factors but also closely tied to geopolitical developments. During periods of international geopolitical tension—such as wars, regional conflicts, or political instability—investors often flock to buy gold as a safe-haven asset, driving its price sharply higher. Conversely, when tensions ease, gold prices may quickly retreat. For instance, at the onset of the Russia-Ukraine conflict in 2022, gold prices surged rapidly, briefly breaking through the $2,000-per-ounce mark. However, as the market gradually digested the impact of the conflict and other factors came into play, gold prices subsequently experienced significant volatility and adjustments. For companies investing in the gold mining industry, these dramatic price swings present both opportunities and substantial risks. If firms ramp up investments to expand production capacity during periods of high prices, only to face a subsequent drop in prices, they could find themselves grappling with sluggish sales and declining profits.
In addition to exploration results and market price factors, unexpected risks to mining investments can also arise from changes in policies and regulations, breakthroughs in technical challenges, as well as force majeure events such as natural disasters. Mining policies and regulations vary significantly across different countries and regions—and these regulations may even evolve over time. For instance, some countries might tighten environmental requirements for mineral resource development, raise tax rates, or impose stricter conditions on the approval and transfer of mining rights. Such adjustments in policies and regulations could directly increase companies' operational costs, undermine project profitability, and even force projects to halt or be canceled altogether.
Technical challenges are also risk factors that cannot be overlooked in mining investments. During the development of mineral resources, companies may encounter various technical hurdles, such as complex mining techniques required under challenging geological conditions, or bottlenecks in ore processing and metallurgical technologies. If enterprises fail to address these technical issues promptly and effectively, it could lead to project delays, increased costs, and even prevent the project from achieving its intended production goals. For instance, in the field of deep-sea mineral resource development, the extreme environmental conditions—such as high pressure, freezing temperatures, and complete darkness—pose enormous difficulties for extraction technologies. Although some technological advancements have already been made, many critical technical challenges remain unresolved. For companies investing in deep-sea mineral development projects, technical risks are a key consideration.
Natural disasters and other force majeure events can also deliver devastating blows to mining investments. Natural catastrophes such as earthquakes, floods, and landslides may damage a mine's infrastructure, leading to production disruptions—and even causing casualties and property losses. In 2019, eastern Australia experienced severe flooding, which affected numerous coal-producing regions. The floodwaters inundated several coal mine shafts, damaged transportation routes and power facilities, and ultimately forced coal production and shipments to come to a halt. As a result, Australia's coal exports plummeted, leaving the affected mining companies grappling with substantial financial losses.
The high-risk nature of mining investments requires investors to proceed with utmost caution when making decisions. Successful mining investments demand that investors possess keen market insight, robust risk-assessment capabilities, strong financial resources, and flexible response strategies. At the same time, companies must also strengthen collaboration with research institutions, financial organizations, and other stakeholders to jointly address the various risks and challenges that may arise during the investment process. Only in this way can they achieve steady growth and secure substantial investment returns in the inherently uncertain field of mining investments. 5
Environmental destruction
The environmental damage caused by mineral resource development is a serious issue that cannot be ignored—it’s like a double-edged sword, bringing economic growth to human society while simultaneously inflicting severe harm on the ecological environment. As global industrialization accelerates, large-scale mining activities have triggered a surge in various environmental problems, posing significant threats to ecological balance, human health, and sustainable development.
In terms of land resources, mineral extraction has caused severe damage and significant land occupation. Open-pit mining, one of the most common methods of mining, often requires the removal of vast areas of topsoil and rock, resulting in the formation of enormous mine pits. For instance, the Bingham Canyon Copper Mine in the United States features an open-pit mine of staggering scale—covering more than 7.7 square kilometers and reaching a depth of 1,200 meters. Such massive mine pits not only directly consume substantial land resources but also lead to fundamental alterations in the surrounding landscape, completely destroying once-fertile farmlands, lush forests, and grasslands, thereby eliminating their original ecological functions and productive capacities. Meanwhile, although underground mining occupies relatively less surface area compared to open-pit methods, it can still trigger serious issues like ground subsidence. Shanxi Province, a major coal-producing region in China, has experienced extensive and long-term underground coal mining activities, leading to widespread ground subsidence across many areas. According to statistics, the cumulative area of ground subsidence caused by coal mining in Shanxi Province has surpassed 5,000 square kilometers, affecting numerous villages and towns. This ground subsidence has not only caused cracks and collapses in countless homes, endangering residents' lives and property, but has also rendered large tracts of arable land unusable for farming, further exacerbating the strain on land resources.
Water resources have also suffered severe pollution and degradation during the mineral development process. Mining activities generate large volumes of wastewater, which often contain a variety of hazardous substances, such as heavy metal ions (including lead, mercury, cadmium, and chromium), acidic or alkaline compounds, organic pollutants, and suspended solids. If this untreated wastewater is discharged directly into the environment, it can cause serious contamination of surface water, groundwater, and soil ecosystems. A prime example is the 2010 water pollution incident involving Zijin Mining Group. At the company's wet-process plant in the Zijinshan Gold (Copper) Mine, a sewage pond leaked, releasing massive amounts of untreated, copper-containing acidic wastewater into the Tingjiang River. This led to a dramatic deterioration in water quality along certain stretches of the river, resulting in widespread fish deaths. Laboratory tests revealed that copper ion concentrations in the Tingjiang River far exceeded regulatory safety levels, posing a significant threat to local fisheries and jeopardizing the drinking water supply for residents. Preliminary estimates indicate that the pollution event caused approximately 3.28 million pounds of dead and poisoned fish solely within the Mianhuatan Reservoir area of the Tingjiang Basin, resulting in substantial direct economic losses. Moreover, dewatering drainage operations associated with mining activities can lower groundwater levels, disrupting the regional water resource balance. This, in turn, leads to the drying up of nearby rivers and lakes, severely impacting agricultural irrigation as well as the availability of clean water for both humans and livestock.
Air pollution is also one of the significant environmental issues arising from mineral resource development. During mining operations, ore transportation, and processing, substantial amounts of pollutants such as dust and exhaust gases are generated. For instance, in coal mining, the excavation, loading, and transportation of coal produce large quantities of coal dust, which, when released into the air, not only degrade air quality but may also trigger respiratory diseases and other health problems. Meanwhile, the combustion of coal and the smelting of ores release massive amounts of harmful gases, including sulfur dioxide (SO₂), nitrogen oxides (NOₓ), carbon monoxide (CO), and more. These gases, once emitted into the atmosphere, can lead to severe weather phenomena like acid rain and smog, posing serious threats to both the ecological environment and human health. According to statistics, in certain regions of China where mining activities are concentrated, airborne dust and harmful gas concentrations have far exceeded regulatory standards, resulting in significantly higher rates of respiratory illnesses among local residents compared to other areas.
Biodiversity is also severely threatened by mineral resource development. Mining activities often destroy the habitats of plants and animals, leading to a decline in biodiversity. During mine construction and extraction, vast areas of forest are cleared, and grassland vegetation is disrupted, leaving many wildlife species without food sources or suitable places to live. Meanwhile, environmental pollution caused by mining—such as soil contamination, water pollution, and air pollution—also adversely affects the survival and reproduction of flora and fauna. In some mountainous regions rich in mineral resources, prolonged mining activities have pushed numerous rare and endangered plant and animal species toward extinction, while significantly undermining the stability and functionality of local ecosystems.
To address the environmental damage caused by mineral resource development, countries around the world are actively implementing a range of environmental protection measures and ecological restoration initiatives. In terms of policies and regulations, many nations have enacted stringent environmental protection laws and guidelines that clearly outline requirements for environmental impact assessments of mineral resource projects, controls on pollutant emissions, and responsibilities for ecological restoration. For instance, China has established a comprehensive legal framework, including the "Environmental Protection Law of the People's Republic of China," the "Mineral Resources Law of the People's Republic of China," and the "Technical Specifications for Ecological Protection and Restoration Management of Mines." These regulations mandate that mining enterprises must adopt effective environmental safeguards and fulfill their ecological restoration obligations while exploiting mineral resources. Companies found in violation of environmental laws will face severe penalties as stipulated by law.
In terms of technological innovation, an increasing number of advanced environmental protection technologies and processes are being applied to the field of mineral resource development. For instance, adopting green mining techniques—such as backfilling mining methods and water-preserving extraction technologies—can significantly reduce damage to land and water resources. Meanwhile, developing highly efficient wastewater treatment technologies, like membrane separation and biological treatment methods, enables mines to achieve compliant discharge standards and promote the recycling of wastewater. Additionally, promoting cleaner production practices—such as implementing cutting-edge ore beneficiation technologies and energy-saving, low-consumption smelting techniques—can minimize the generation of exhaust gases and industrial waste residues. Furthermore, leveraging tools like Geographic Information Systems (GIS) and Remote Sensing (RS) allows for real-time monitoring and assessment of mine environments, enabling prompt identification and resolution of environmental issues.
Many regions have actively launched ecological restoration initiatives, achieving remarkable results. Shanxi Zhongmei Pingshuo Group Co., Ltd. has adhered to the principle of "mining and restoring simultaneously" throughout its coal extraction process, successfully establishing an integrated "mining—transportation—disposal—restoration" model that seamlessly combines production with ecological rehabilitation. Through long-term collaboration with relevant academic institutions and by incorporating cutting-edge international ecological restoration concepts, the company has restored 4,667 hectares of land, creating ecosystems that are not only more structurally sound but also significantly more efficient in terms of functionality compared to the original landscape. During the restoration process, the company has employed a range of scientifically advanced techniques, including land leveling, soil improvement, and vegetation recovery. For the mined-out pits, they first carry out backfilling and leveling, followed by applying suitable topsoil and planting native plant species tailored to local growing conditions. Over the years, these dedicated efforts have transformed once-devastated mining areas into lush, green landscapes, dramatically enhancing the local ecological environment. The project has yielded substantial ecological, social, and economic benefits, earning the company prestigious accolades such as the China Baosteel Environmental Excellence Award. This initiative has set a valuable precedent and provided a practical model for large-scale ecological restoration in China's major coal-mining regions.
Inner Mongolia Guoneng Juneng Group Co., Ltd.'s Heidagou Open-Pit Coal Mine has also actively explored innovative approaches to ecological restoration. Located at the intersection of Inner Mongolia, Shanxi, and Shaanxi provinces (regions), the mine faces a fragile ecological environment, severe soil erosion, and vegetation coverage that remains below 25%. While undertaking large-scale coal resource development, the Heidagou Open-Pit Coal Mine has earnestly implemented Xi Jinping's Thought on Ecological Civilization, synergistically advancing carbon reduction, pollution control, green initiatives, and economic growth. Guided closely by the nation's major strategic initiative for ecological protection and high-quality development in the Yellow River Basin, the mine has successfully pioneered a cost-effective, high-standard model for mine-site ecological restoration. By integrating coal mining operations with ecological conservation efforts, the mine has achieved integrated mining and restoration practices. It has also fully embraced the development of a green economy, transforming ecological resources into marketable assets. Additionally, the mine is vigorously working to establish a National Mining Park, positioning itself as a new hub for eco-friendly industrial tourism within the region. Over the years, the mine has cumulatively restored 6,567 hectares of land, creating eight distinct ecological functional zones. As a result, vegetation coverage has surged to over 80%, and the land reclamation rate has reached 100%. These achievements have not only fostered the coordinated development of ecological, environmental, social, and economic benefits but have also earned the mine prestigious national-level accolades, including "National Green Mine," "China's Most Beautiful Mine," "National Industrial Tourism Demonstration Base," and "National Mining Park." The Heidagou Open-Pit Coal Mine has thus set a remarkable "Chinese model" for ecological restoration in ecologically vulnerable areas of Northwest China.
The environmental damage caused by mineral resource development is a complex and pressing issue that demands concerted efforts from governments, businesses, and all sectors of society. Effective policy measures, advanced technological solutions, and robust management practices must be implemented to strengthen environmental protection and ecological restoration, thereby fostering a balanced relationship between mineral resource exploitation and ecosystem conservation. Only in this way can we meet the current generation's demand for mineral resources without compromising the interests of future generations, ultimately safeguarding the planet's ecological health and ensuring the sustainable development of both humanity and our shared global community.
Reserves in Dynamic Change
Mineral resource reserves are not static, fixed figures—they are instead in a state of dynamic change. This inherent characteristic means that human understanding and utilization of these resources are constantly evolving, requiring ongoing exploration and adaptation. Such dynamic shifts primarily stem from a variety of factors, including continuous advancements in exploration technologies, the ongoing discovery of new mineral deposits, resource depletion caused by mining activities, and the ever-changing technological and economic conditions. These factors intertwine with one another, collectively shaping the dynamic patterns of mineral resource reserves.
Advances in exploration technology play a crucial role in driving the dynamic changes in resource reserves. With the rapid development of science and technology, an increasing number of cutting-edge exploration techniques have emerged, significantly enhancing humanity's ability to detect and understand underground mineral resources. Among geophysical exploration methods, high-precision gravity, magnetic, and seismic surveys enable deep insights into subsurface geological structures and mineral distributions through precise measurement and analysis of Earth's physical fields. In the field of oil exploration, the widespread adoption of 3D seismic technology has dramatically improved the accuracy of oil prospecting. By creating three-dimensional images of underground geological formations, this technology allows for clearer identification of potential oil and gas reservoir locations and their shapes, thereby boosting the confirmed volume of oil reserves. According to statistics, in regions where 3D seismic exploration has been implemented, the discovery rate of oil reserves has increased by 30% to 50% compared to traditional 2D exploration techniques.
Geochemical exploration techniques involve analyzing the chemical element content and distribution patterns in samples such as soil, rocks, and stream sediments to identify geochemical anomalies indicative of mineral resources, providing crucial clues for mineral exploration. For instance, when searching for gold deposits, analyzing trace elements in soil can help pinpoint areas where gold minerals may be present, enabling targeted and more efficient follow-up exploration efforts. This technique has played a pivotal role in uncovering hidden ore deposits that would otherwise have remained undetected, ultimately boosting the overall reserves of mineral resources.
The discovery of new mineral deposits is another critical factor driving the dynamic changes in resource reserves. Geologists continuously uncover fresh sources of mineral resources through in-depth geological research, extensive field investigations, and ongoing innovations in geological theory. For instance, the Budunwula silver mine in Inner Mongolia has seen its silver reserves soar from an initial 859.8 tons to 11,114 tons—equivalent to the addition of 10 large-scale silver deposits. This groundbreaking discovery has significantly boosted China’s reserves of silver resources, providing a stronger foundation for the sustainable growth of the silver industry. According to relevant statistics, over the past decade, global annual discoveries of various mineral resources have averaged an increase of approximately 3% to 5%, with these newly identified deposits playing a vital role in expanding the world’s overall resource reserves.
Mining activities are undoubtedly the direct cause of declining resource reserves. As mineral resources continue to be extracted, proven reserves are gradually depleted. In the process of mining coal and metal ores, ore is continuously brought to the surface, leading to a steady reduction in resource availability. According to data from the International Energy Agency (IEA), global annual coal production stands at approximately 8 billion tons, further accelerating the decline in coal reserves. In some traditionally rich coal-producing regions—such as the Appalachian area in the United States and Shanxi Province in China—intensive mining over extended periods has already resulted in significant reductions in coal reserves. In fact, several mines have even been shut down altogether due to resource exhaustion.
Changes in technological and economic conditions can also significantly impact resource reserves. When technological advancements make previously difficult-to-extract or economically unviable mineral resources now feasible to mine and profitable, resource reserves naturally increase accordingly. Historically, the development of deep-sea mineral resources was considered challenging due to technological and cost constraints. However, with the continuous advancement of deep-sea exploration and extraction technologies—such as the emergence of deep-sea robots and specialized mining vessels—exploiting these resources has gradually become a reality. It is estimated that vast quantities of polymetallic nodules, cobalt-rich crusts, and hydrothermal sulfides lie beneath the world's deep-sea beds, holding enormous potential reserves. Once these resources can be commercially mined, they will dramatically boost global mineral resource reserves.
Market prices, policies, regulations, and other economic and policy factors can also indirectly influence resource reserves. When the market price of a particular mineral resource rises, companies may increase their mining efforts, accelerating the consumption of existing reserves. Conversely, when prices fall, mining activities may slow down, leading to a reduced rate of reserve depletion. On the policy front, some countries may introduce measures that encourage exploration and development, thereby boosting the discovery of new deposits and expanding resource reserves. On the flip side, stringent environmental or resource conservation policies could restrict mining activities, directly impacting the dynamic changes in resource availability.
The dynamic nature of mineral resource reserves requires us to maintain a dynamic mindset and a scientific approach throughout the process of resource development and management. We must continuously strengthen research and development in exploration technologies, actively seeking new reserves while simultaneously planning and scientifically extracting existing resources to enhance efficiency—thus meeting the challenges posed by the ever-changing availability of reserves and ultimately achieving sustainable development and utilization of mineral resources.
Multicomponent Symbiosis
Multi-component symbiosis is one of the key characteristics of mineral resources, offering humanity a wealth of resource treasures while simultaneously posing significant challenges to exploration and development technologies. So-called multi-component symbiosis refers to the frequent coexistence of two or more economically valuable metallic or non-metallic elements within the same ore deposit, tightly intergrown with each other to form intricate mineral systems. This symbiotic phenomenon arises from Earth's long and complex geological evolution, where distinct mineralization processes have overlapped under specific geological conditions, leading to the concentrated accumulation of multiple useful components in a single region.
Taking the tin-polymetallic deposit in southeastern Yunnan as an example, the newly discovered tin-polymetallic resources in this mineral belt exhibit typical characteristics of multi-component coexistence. The ore composition and structural features are exceptionally complex, with minerals closely interlocked and intimately embedded within one another. Among them, metallic minerals predominantly occur as sulfides, accompanied by minor amounts of oxides and secondary minerals, resulting in a relatively high sulfur content. In addition to the primary tin element, this type of ore also hosts several other metal elements in symbiosis, including copper, lead, and zinc. Given the intricate nature of this ore system, conventional single-metal extraction techniques struggle to achieve efficient exploitation and utilization. Moreover, constrained by current polymetal separation technologies, the final concentrates often contain significant impurities from each other. As a result, it becomes extremely challenging to selectively produce high-quality, single-metal concentrates while simultaneously maintaining high recovery rates.
To tackle this challenging issue, the Chengdu Comprehensive Utilization Institute of the China Geological Survey has undertaken in-depth research. Researchers conducted meticulous process mineralogical studies on three types of ores found within the study area: primary chalcopyrite-cassiterite ore (tin-bearing copper ore), primary chalcopyrite-sphalerite-cassiterite ore (tin-copper-zinc ore), and secondary copper-lead-zinc-cassiterite ore (surface-level semi-oxidized tin-copper-lead-zinc ore). On this basis, they successfully completed beneficiation tests for both the tin-copper-zinc ore and the tin-copper-lead-zinc ore. Through continuous exploration and innovation, they ultimately recommended a prioritized flotation–gravity separation process as the optimal technical solution.
This process technology solution boasts significant advantages. The process structure is simple and easy to implement in actual production, while the operation procedure is also straightforward to control. The方案 effectively recovers five primary metallic minerals—copper, lead, zinc, tin, and sulfur—and the resulting products exhibit outstanding technical performance. In addition to recovering the main metallic minerals, the accompanying silver is also efficiently enriched, and other coexisting components in the ore are similarly achieved through comprehensive recovery. To further enhance the beneficiation efficiency, the project has developed two new reagent products: an adjusting agent (EMT-104) and another (EMT-12), along with a selective collector named EMS-001. These innovative reagents demonstrate excellent performance; for instance, EMT-12 is specifically designed to selectively suppress easily floated zinc minerals during preferential flotation, while EMS-001 serves as a highly selective collector-frother for non-ferrous metal sulfide ores. In certain mixed-flotation processes, EMS-001 can be used for simultaneous copper-lead flotation, whereas in preferential-flotation scenarios, it proves ideal for prioritizing lead and zinc recovery. Meanwhile, EMT-104 effectively activates sulfur minerals under neutral or weakly alkaline conditions, ensuring efficient sulfur recovery. These newly developed beneficiation reagents have successfully undergone applicability verification in large-scale beneficiation tests, ultimately becoming standard products tailored specifically for this type of ore.
This achievement ranks among the leading levels in the comprehensive utilization of similar ores. After being reviewed and approved by the China Geological Survey, the expert panel unanimously agreed that the project has successfully passed the acceptance process and rated its outcomes as outstanding. Following the implementation of a tailored beneficiation and comprehensive utilization technology plan—as well as product development strategies—tailored to the specific characteristics of the ore, the mining enterprise has realized remarkably significant economic benefits. Preliminary calculations based on the beneficiation technical indicators obtained from expanded-scale trials, using December 2010 metal prices, indicate that a processing plant handling 1,000 tons per day could generate an annual output value of up to 584.69 million yuan, with annual profits and taxes reaching 485.76 million yuan. Moreover, the innovative process technologies, novel reagent products, and other technical achievements developed through this project have already been validated and applied in other similar multi-metal ore beneficiation studies, demonstrating their potential for widespread adoption in the efficient utilization of complex coexisting mineral resources across various mining industries.
The comprehensive development and utilization of multi-component coexisting mineral resources not only maximize resource efficiency and enhance economic benefits but also help reduce waste emissions and minimize environmental impact, yielding significant environmental advantages. In today’s context of increasingly scarce resources, strengthening research and promoting technologies for the integrated exploitation of these multi-component coexisting minerals are crucial for ensuring a sustainable supply of resources and fostering long-term economic growth. 8
Quality Differences
Quality variability is one of the prominent characteristics of mineral resources, primarily reflected in several aspects, such as the grade of the ore, the complexity of its texture and structure, as well as the types and quantities of impurities it contains. Ore grade serves as a key indicator for assessing ore quality, directly reflecting the concentration of valuable components within the ore. For instance, in iron ores, the iron content level determines the ore's grade: high-grade iron ores typically contain more than 60% iron, whereas low-grade iron ores may have an iron content below 50%. Such variations in ore grade significantly influence both the methods used for mining and processing mineral resources, as well as their economic viability.
The application and value of iron ores with different grades in steel production differ significantly. High-grade iron ore, with its high iron content and minimal impurities, can markedly enhance both the efficiency and quality of steel production during the smelting process. Using high-grade iron ore not only reduces energy consumption and raw material usage in smelting but also lowers overall production costs. Moreover, steel products made from high-grade iron ore boast superior quality, enabling them to command higher prices and stronger competitiveness in the market. For instance, Baosteel sources some of its high-grade iron ore from Vale, a Brazilian company—these ores contain iron levels as high as 65% or more. Leveraging these premium-quality iron ores, Baosteel produces advanced steel grades that are widely employed in industries such as automotive manufacturing and aerospace, where steel quality is critically demanding. As a result, the company has reaped substantial profits from this strategic partnership.
In contrast, the development and utilization of low-grade iron ore face numerous challenges. Due to its lower iron content, significantly more energy and resources are required during the smelting process to extract the iron element. Additionally, more complex beneficiation and smelting techniques must be employed to remove impurities. This not only drives up production costs but may also place greater strain on the environment. However, low-grade iron ore is by no means valueless—when paired with appropriate technological solutions and economic analyses, it can still be effectively utilized. In certain regions, advanced beneficiation technologies such as magnetic separation, flotation, and gravity concentration, when combined, can efficiently enrich iron concentrate from low-grade ores, boosting iron recovery rates. Meanwhile, some enterprises are leveraging technological innovation to develop specialized smelting methods tailored for low-grade iron ore, such as direct reduction ironmaking, thereby opening up new avenues for its effective utilization.
Grading and utilizing mining operations based on differences in ore quality is a crucial strategy for achieving efficient development of mineral resources. Graded mining allows for the rational planning of extraction sequences and methods according to factors such as ore grade and mining difficulty, prioritizing the extraction of high-grade, easily accessible ores to enhance efficiency and reduce costs. For high-grade ores, advanced, precision mining techniques are employed to ensure both ore quality and recovery rates; meanwhile, for low-grade ores, suitable extraction and beneficiation processes are selected based on their specific characteristics, enabling the maximum possible utilization of these valuable resources.
Graded utilization involves applying the products obtained after ore processing—based on their quality and performance—to different fields and industries. High-purity, high-quality mineral products can be used in advanced manufacturing and cutting-edge technology sectors, meeting the stringent material-performance requirements of specialized applications. Meanwhile, products of slightly lower quality are suitable for general industrial applications or even the construction sector, where material performance demands are relatively more moderate. For instance, in copper ore utilization, high-grade refined copper is ideal for producing precision electronic components such as chip pins and circuit boards—applications that place extremely high demands on copper’s purity and conductivity. In contrast, lower-grade copper products can be employed in manufacturing building materials like copper pipes and doors/windows, effectively satisfying the construction industry’s basic needs for material strength and corrosion resistance.
Through tiered mining and utilization, not only can we enhance the efficiency of mineral resource use and reduce waste, but also improve the economic benefits for enterprises. A well-designed tiered strategy enables companies to flexibly adjust their production plans based on market demand and product prices, allowing them to produce goods that meet consumer needs—and ultimately gain a competitive edge in the marketplace. Moreover, tiered utilization helps lower production costs by efficiently allocating ores and products of varying quality to appropriate production stages and application areas, preventing the overconsumption of high-quality resources as well as the wasteful idling of lower-grade materials, thereby achieving optimal resource allocation.
Quality variability is an inherent property of mineral resources. By fully recognizing and leveraging this characteristic, coupled with scientifically sound and rational approaches to tiered mining and utilization, we can maximize the value of mineral resources, thereby achieving efficient resource use and fostering sustainable development.
