mineral processing of low grade iron ore india

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.
