Magnetic Separation and Iron Ore Beneficiation

2018-10-4  The trapped magnetic particles are easily washed out when the applied field is reduced to zero. Magnetic separators of this type are useful for the concentration or removal of fine magnetic particles when processing of iron ore for pellet feed. Magnetic separators are integral part of the low grade iron ore beneficiation systems.

Developments in the physical separation of iron ore

2015-1-1  It is very difficult to produce a high-quality iron ore concentrate by magnetic 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 the magnetite particles, while drum MIMS (0.4 T middle-intensity magnetic separators) are used to recover the martite grains.
