  • 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 Worlds early history of production of iron. Since the 1950s North Americas main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25 30 Fe.
