  • iron III

    The alteration of the original rock to iron ore involved two processes that probably occurred at essentially the same time: 1 oxidation of the iron minerals caused by waters circulating through the rocks The soluble ferrous iron in the minerals was converted to insoluble hematite, geothite, or limonite. and 2 Continued circulation of water through the rocks gradually dissolved the silica from the iron silicates

  • Iron ore

    Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities
