Extraction of metals/Iron - Wikiversity

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.
