6. Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides, carbonates and sulphates. 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 …

Modern practice, then, is to crush the ore as it comes from the mine in two steps to a maximum size of ½" without the use of water except as a spray to remove dust. Three stages are only needed if the primary machine is called upon to take lumps of exceptional size, such as are encountered when mining is done by power-shovel.
