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

2021-8-24  The yield of the first magnetic separation step was 62.93%. Therefore, it produced 4.352 kg tailing of 20.16% Fe. In order to increase the total iron recovery, it was decided to enrich the tailing of the first magnetic separation step. Hence, it was initially ground in a dry ball mill to particle sizes less than 425 μm and then it was fed to the magnetic separator. A concentrate of 38.58% Fe, with a yield of 8.31% was produced. The iron grade of this concentrate is near the iron grade of the initial low-grade iron ore.

DRY BENEFICIATION OF LOW-GRADE IRON ORE FINES

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic [1,5]. Wet and dry low-intensity magnetic separation (LIMS) techniques are used to process ores with strong magnetic properties such as magnetite while wet high-intensity magnetic separation is used to separate the Fe-bearing minerals with weak magnetic properties such as hematite from gangue minerals. Iron ores such goethite and limonite are commonly found in tailings and does not separate very well by either technique [1,5]. Magnetic methods present challenges in terms of their low capacities and in terms of the requirement for the iron ore
