There are over 80 types of minerals widely used around the world, among which nine—iron, copper, bauxite, lead, zinc, nickel, phosphate, tin, and manganese—are particularly important due to their high value and significant international trade volume. The global mining industry is notably concentrated, with 70-75% of production concentrated in just over ten countries, particularly a few industrialized nations. Russia and the United States are the two largest mining countries in the world, followed closely by Australia and South Africa.
Iron Ore
Australia has the largest reserves of iron ore, with a total resource amount of 850 billion tons and proven reserves of 400 billion tons, containing 930.8 billion tons of iron. Major deposits are found in Brazil (17.5%), Russia (16.8%), Canada (11.7%), Australia (11.5%), Ukraine (9.8%), India, China, France, South Africa, Sweden, and the United Kingdom. Rich iron mines total 140 billion tons, predominantly in Australia, Brazil, Russia, Ukraine, India, Sweden, and South Africa. Australia leads with abundant high-grade iron ore reserves, exporting a significant amount to major steel-producing countries like China and Japan. Brazil ranks second with substantial iron ore reserves and an important position in the international iron ore market. Russia also has considerable iron ore reserves, primarily located in the Kursk Magnetic Anomaly region. China has rich iron reserves, but many are of lower quality, making extraction and beneficiation more costly. In 2024, global iron ore production is expected to increase by over 66 million tons from the previous year, mainly from India, China, Australia, Brazil, Ukraine, and Liberia. Notably, the contribution of non-mainstream countries to global iron supply is growing, with India’s production expected to increase by about 20 million tons to 300 million tons in 2024, representing a 7% increase. China’s domestic iron concentrate production is projected to increase by 15 million tons, a 5% rise, under the promotion of the cornerstone plan.
Copper Ore
The largest copper deposit is located in Chile, with foreign statistics indicating reserves of 641 million tons (metal content). About 70% of reserves are found in four major geological-geographical areas: the porphyry copper districts in Chile and Peru, the copper belt in the western United States, the sandstone copper deposits in northern Zambia and adjacent Zaire, and various copper deposits in Russia and Kazakhstan. By country, Chile ranks first, followed by the United States, Australia, Russia, Zambia, Peru, Zaire, Canada, and Kazakhstan. Chile, with its favorable geological conditions, holds the world's largest copper reserves and hosts several world-class large copper mines, such as the Escondida mine. Peru ranks second with ample copper resources, while Australia also has significant copper reserves and holds a notable share in the global copper market.
Bauxite
Bauxite, the main raw material for aluminum production, is primarily produced in Australia and Guinea. The total global bauxite reserves exceed 2.5 billion tons, mainly distributed in Guinea, Australia, Brazil, Jamaica, and India, with these five countries accounting for 60% of overall reserves. Guinea has the largest bauxite reserves, followed closely by Australia, making these two countries the primary suppliers of bauxite globally. Vietnam and Brazil also have relatively substantial bauxite reserves, occupying a certain position in the global bauxite resource landscape.
Lead Ore
Russia, the U.S., Australia, and Canada each produce over 300,000 tons of lead ore annually, with total annual production remaining stable between 3.4 and 3.6 million tons since the 1970s. These four countries are among the top producers of lead ore. Additionally, Peru, Mexico, Morocco, and Yugoslavia also contribute significantly to global lead ore production.
Tin Ore
The main tin-producing regions are located in Southeast Asia and South Asia, with the total proven reserves of tin ore amounting to 10.14 million tons. Tin deposits are found in a belt-like distribution, with the Pacific region being the primary area of abundance. The Southeast Asia tin belt accounts for 60% of the world's total reserves. Countries with significant reserves include Indonesia, China, Thailand, Malaysia, and Bolivia.
#### Nickel Ore
Indonesia holds the largest nickel reserves in the world. In recent years, Indonesia's influence in the global nickel market has grown, with high production levels. Australia, Brazil, Russia, New Caledonia, the Philippines, China, Canada, the U.S., and Colombia are also major nickel-producing regions.
Gold Ore
Western Australia is a significant gold-producing area, with total global reserves exceeding 41,000 tons. Gold deposits are mainly found in South Africa (69%), Russia (approximately 10%), the U.S. (9%), and Canada. Global gold production sources are quite dispersed. Australia ranks high in gold production due to its rich reserves, with Western Australia being a crucial area. Russia also has high gold production levels, with many deposits in Siberia. South Africa, once the world's largest gold producer, has experienced a decline in production in recent years but still maintains substantial reserves, ranking favorably in global production. Other countries such as the U.S., Peru, Indonesia, Brazil, Canada, and China also have notable gold production levels.
