  • iron ore concentration Archives International Mining

    New Steel’s technology can deliver a concentrate with iron content up to 68% Fe from poor ore with content up to 40% Fe, depending on its chemical and mineralogical composition, according to Vale. Currently, this concentrate is produced by flotation, which uses water. In flotation, the tailings are usually disposed of in dams, but, with the dry concentration technology developed by New Steel, the tailings

    Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.

  • The Effect of Slurry Concentration on Mining Iron Ore

    In short, increasing slurry density is beneficial to mining iron ore, and the water and power consumption of per ton of material is less. General principles of iron ore slurry concentration are coarse grain with high concentration, fine with low concentration; roughing by high concentration, featured by low concentration. The range of iron ore concentration of reverse flotation is generally 22~40%.
