Iron ore - Wikipedia

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. Magnetite is magnetic, and hence easily separated from the gangue minerals and,Raw material - Wikipedia,Iron ore. Iron ore can be found in a multitude of forms and sources. The primary forms of iron ore today are Hematite and Magnetite.While iron ore can be found throughout the world, only the deposits in the order of millions of tonnes are processed for industrial purposes.
