Feb 15, 2021 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. Extraction of Raw Materials (1) The key raw materials in steelmaking include iron ore, coal, limestone, and recycled steel (not extracted). Actual steel is mostly iron ore and less than 2% carbon, the other materials are used in the manufacturing of crude steel. Iron ore is mined
