extraction of iron from haematite ore by tutor

Extraction Of Iron - SlideShare. The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide - Fe2O3). o The iron ore contains impurities, mainly silica (silicon dioxide). o Since iron is below carbon in the reactivity series, iron in the ore is reduced to iron metal by heating with carbon (coke).
