Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries ...

A wide variety of minerals can be classified as "non-fuel", including precious metals, base metals, industrial minerals, and materials used for construction. Non-fuel minerals are those not used for fuel, such as oil, natural gas and coal. Once non-fuel minerals are used up, there is no replacing them. However, many can be recycled continuously.
