Magnetite Iron Ore Separation Method

For magnetite and titanium magnetite ores it is possible to use technology with the separation of concentrate before the last grinding stage. The possibility of staged separation of iron concentrate is due to different physical-mechanical properties of magnetite and rock minerals. The results of industrial and laboratory tests on the use of special magnetic separators with special structure .
