ADVANCES IN MAGNETIC SEPARATION OF ORES

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

Maximizing the recovery of fine iron ore using magnetic ...

advantage of magnetic separation over flotation, in fine iron ore beneficiation is that treatment of –10 µm iron ore is possible – in flotation the feed is deslimed at 10 µm and the –10 µm stream is considered to be final tailings even though there is often a significant amount of contained iron ore. The recovery of fine iron ore by ...
