     · 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 with coke and limestone and 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.

    Lime in the Steel Industry | Graymont

    Lime is used to convert iron into 'pig iron'. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces. Lime removes impurities (silica, phosphorus, sulfur ...
