the iron mineral in the single magnetic iron ore is mostly magnetite. because the magnetite ore has simple composition,strong magnetism and easy to separate, so the weak magnetic separation process is often used to deal with single magnetic iron ore.2) polymetallic magnetic iron ore weak magnetic separation froth flotation process
