Iron Ore Department for Energy and Mining

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.

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
