The Direct Reduction of Iron Ore
The iron ore from which iron and steel are made is an oxide, that is, a chemi cal compound of iron (Fe) and oxy gen (0). Common forms of ore are hematite (Fe20a) and magnetite (Fea04)' For the ore to be made into iron the oxygen atoms must be separated from the iron atoms by the process known as reduction. The separation
