ADVANCES IN MAGNETIC SEPARATION OF ORES

2016-12-4  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 resources, as well as disposal systems and some- times complicated water reclamation systems. Some of the new low grade iron ore discoveries in Canada are in areas where the climate encourages use of dry processing methods.
