  • Different Types of Iron Ore - Mineral Processing

    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 Bessemer...

  • Redox Behavior of Magnetite: Implications for

    2019-12-12  The factors controlling rates of contaminant reduction by magnetite (Fe3O4) are poorly understood. Here, we measured the reduction rates of three ArNO2 compounds by magnetite particles ranging from highly oxidized (x = Fe2+/Fe3+ = 0.31) to fully stoichiometric (x = 0.50). Rates of ArNO2 reduction became almost 5 orders of magnitude faster as the particle stoichiometry increased from x =

    Regular magnetite is not formed magnetic, and in fact, most magnetite cannot be magnetized at all. In order for magnetite to become magnetized, it must have a certain crystal structure and chemical composition.
