  • Removal of Phosphorus From High Phosphorus Iron Ores by ...

    The reserves of high phosphorus iron ore accounts for 14. 86% of total reserves and reaches 7. 45 Gt. The content of phosphorus is generally a few times or even hundreds of times higher than that of common iron oresL†. In high phosphorus iron ores, phosphorus coexists with other minerals in the form of apatite or fluorapatite, disseminates ...

  • Iron ore - Wikipedia

    Bog ore often has a high phosphorus content (Gordon 1996, p. 57). The strength and hardness of iron increases with the concentration of phosphorus. 0.05% phosphorus in wrought iron makes it as hard as medium carbon steel. High phosphorus iron can also be hardened by cold hammering. The hardening effect is true for any concentration of phosphorus.

  • Different Types of Iron Ore - Mineral Processing Metallurgy

    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 limit. A Bess
