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.

The concentrated ores can be converted into metal oxide by using calcination or roasting based on the nature of the ore. The process of heating carbonate ore strongly in the absence of air is called calcination. Metals such as zinc (Zn), tin (Sn), lead (Pb), and iron (Fe) can be extracted by the process of calcination.

Extraction of iron in the blast furnace Iron ores contain iron oxide compounds such as haematite, Fe 2 O 3 . To obtain pure iron the oxygen must be removed from these compounds, meaning they get reduced . The reduction process is carried out in a blast furnace which contains the following materials: Iron ore

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
