The reason for the position in the metal league table is that about 90% is used as part of the process in the production of steel and cast iron, and also as an alloy in speciality steels. It is usually added in the form of a ferroalloy, such as ferro-manganese and silico-manganese for convenience and to help the steel maker's calculations.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).. Iron ore is the source of primary iron for the world's iron and steel industries.
The reason that mining companies went through the trouble of blasting tunnels so far underground was the quality of the hematite ore; the Soudan Mine had ore so pure that two pieces could be welded. The bedrock, known as taconite, also contained iron, but in a much lower concentration.
Smelting is the process by which an ore mineral is reduced to the metal by heating with a reducing agent such as carbon. Smelting is a major source of atmospheric pollution, smelters produce 8% of the global emmisions of sulphur dioxide the main cause of acid rain.
