Top Largest Deposits of Metals Around the World

Time to Read: 2 m 43s

Iron, the main ingredient of steel, is one of the most important elements on earth. The reddish-brown metal is often found in large mineral deposits of sedimentary rocks.

Metal deposits contain significant amounts of metallic elements, such as gold, copper, and iron. Deposits which can be economically extracted for human use are classified as ores. To be commercially viable, iron ores must contain about 60 percent iron.

Iron ores include the oxides hematite, magnetite, limonite, and goethite, as well as silicates (mixed with silicon and oxygen) and carbonates (mixed with carbon and oxygen). These ores are spread across every continent of the globe and provide a great source of wealth for both local and foreign investors.

Iron Ore Reserves by Country

The continent of Antarctica contains large mineral and metal deposits, but as of the Antarctic Treaty signed in 1998, no commercial mining is allowed there. The following countries produce the largest amounts of iron ores (Note: the general ranking and total figures will vary depending on types of ores produced and the method of reporting).


As of 2015, Australia produced 817,000,000 metric tons of iron ore, mostly from its Western regions – the largest amount of any country. Australia has a total of 17 percent of the accessible reserves of iron ore, the largest deposits in the world.


Brazil came in second with 397,000,000 metric tons of iron ore produced in 2015, or 12 percent of the total world production. Brazil has the second largest deposits of iron ore and some of the largest mines in the world.


Though China’s iron ore production is calculated differently than in other countries, it was estimated that in 2015, China produced approximately 375,000,000 metric tons, or the third largest of global production. The country has the fourth largest iron ore reserves in the world.


India has the fifth largest reserves of iron ore. Its 2015 production was 156,000,000 metric tons.


Russia produced 101,000,000 metric tons of iron ore in 2015. The country has the third largest reserves, and production comes mainly from Central Russia, Siberia, and the Urals.

South Africa

In 2015, South Africa produced 73,000,000 metric tons of iron ore. Seventy percent of South African iron ore is produced by Kumba, a leading supplier of seaborne iron ore.


In 2015, Ukraine produced the 7th largest amount of iron ore at 67,000,000 metric tons. Ukraine has 18 per cent of the global total of accessible reserves, the largest potential amount of any country.

United States

The United States was the 8th largest producer of iron ore in 2015, with a total of 46,000,000 metric tons produced from mines in Michigan, Minnesota, and Utah.


Canada’s 2015 production of iron ore equaled that of the United States, at about 46,000,000 metric tons, depending on the reporting source.
