  • Iron ore

    Lowergrade 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, highquality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

  • What Is Iron Ore Beneficiation? (with pictures)

    Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. Highgrade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.
