— Iron is extracted from its ore, haematite, by reduction with carbon. This takes place in a blast furnace (named after blasts of air [20% oxygen], heated to 1000 °C, which are blasted into the bottom of the furnace): A mixture of crushed iron ore, coke (an almost pure form of carbon) and limestone is fed into the top of the blast furnace.

Iron(III) oxide + carbon → iron + carbon dioxide. 2Fe 2 O 3 (s) + 3C(s) → 4Fe(s) + 3CO 2 (g) Carbon is more reactive than iron. The iron oxide is reduced by the carbon (the oxygen is removed) to form metallic iron. The sodium carbonate fuses easily and brings the iron oxide into close contact with the carbon.
