Magnetic Separation Values Of Ore :

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

2007-2-15  Effective separation of iron values from iron ore slimes using a wet magnetic separator and selective magnetic coating is reported. The selectivity of coating for enhancing the magnetic response of iron particles was achieved by controlling the surface properties of the particles, i.e., electrokinetics potential, through pH adjustment and use of sodium hexa-metaphosphates as the dispersant.
