How is iron extracted from its ore? It’s a long process which begins with Concentration through calcination roasting. Concentration removesthe water and other volatile impurities such as sulphur and carbonates. This concentrated ore ismixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in theblast furnacethat extraction of iron occurs.

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed withcoke and limestoneand then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

There is evidence that meteorites were used as a source of iron before 3000 bc, but extraction of the metal from ores dates from about 2000 bc. Production seems to have started in the copper-producing regions of Anatolia and Persia , where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron to accumulate on the bottoms of copper smelting furnace s.

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.
