Iron OreScrap MetalCoalLimestoneAlloying ElementsIron occurs very rarely as a pure metal in the earth’s crust. On the other hand, there is plenty of iron which is chemically bonded, in association with other elements such as oxygen and sulphur. The most abundant elements in the earth’s crust, in named order, are: oxygen, silicon, aluminium and iron. For the extraction of metallic iron, the compounds formed between iron and oxygen, so-called oxides, play a wholly dominant role. The iron ore mineral is called magnetite (black ore) or hematite (bloodstone ore),
