How iron is made

The ingredients to make useable iron were limestone, ironstone, coke and air. The coke is the fuel and the ironstone provides the iron ore. Ironstone is first roasted in calcining kilns, located next to the blast furnaces, to remove impurities. The air, or blast, was blown into the

The Making of Iron Steel

2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).
