Iron Ore Processing Diagrams

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.7.
