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

Magnetic Elutriation Technology for Clean and Efficient

Magnetic elutriation improves the quality of low-grade domestic iron ore by using an alternating-current, pulsed-magnetic field to clean iron ore into a highly refined product. This innovative process differs from conventional drum type magnetic separation systems by using permanent magnets that cause magnetic entrapment.
