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

Iron ore classification: Critical insights for resource

A powerful iron ore classification system is a critical prerequisite. Without a sufficiently and appropriately characterised resource, modelling will be inaccurate reducing an organisations ability to implement cost reductions and productivity gains across the iron ore value chain.

Ore - Wikipedia

  

2019-10-15  An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit.[1] The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or

Iron ore - Wikipedia

  

2019-10-15  Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Deposits of mechanical origin, however, are susceptible of subdivision if we are sufficiently interested in them; for example, mechanical concentration of talus deposits is due to gravity alone, that of most sedimentary rocks to the of marine waters, that of others to
