Lowgrade ironbearing formations mean those commercial deposits of ironbearing materials not including paint rock located beneath the surface of the earth which in their natural state require beneficiation to make them suitable for blast furnace use and which after such beneficiation produce in tonnage less than 50 percent of iron ore concentrates from the tonnage of lowgrade ironbearing formations delivered to a beneficiation.
01 beneficiation method of magnetite ore the main iron mineral contained in magnetite ore is ferroferric oxide fe3o4 magnetite contains about 85 of iron ore the hardness of the ore is between 55 and 65 and the specific gravity is between 46 and 52 for its strong magnetism weak magnetic separation is the main beneficiation
