EtymologyCharacteristicsChemistryPropertiesDistributionSignificanceResourcesSourcesMagnetite is an iron oxide with the chemical formula Fe3O4. Actually, it is a mixture of two iron oxides, FeO and Fe2O3. Therefore, we can show it as FeO183Fe2O3. According to the IUPAC nomenclature, its name is iron (II, III) oxide. But, commonly we name this as ferrous ferric oxide. Magnetite got its name because it is a magnet.Live Chat

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore this is the so called BessemerLive Chat
