ADVANCES IN MAGNETIC SEPARATION OF ORES

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

Developments in the physical separation of iron ore ...

01/01/2015  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.
