Developments in the physical separation of iron ore
It is very difficult to produce a high quality iron ore concentrate byic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90 75 μm. Drum LIMS are then used to take out theite particles, while drum MIMS 0.4 T middle intensityic separators are used to recover the martite grains. SLonic separators are subsequently
