magnetic separation process iron ore

An implementation of twostep concentration afterpurification allowed increasing the iron content in the concentrate up to It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase socalled wet separation Fig 5 shows the iron ore after the process of magnetic separation

Iron ore beneficiation is the process of purifying raw iron ore before smelting it in various ways to purify it along with several stages of magnetic separation 05 inches 12 millimeters or less and is then passed on to a flotation process

The Ore of Iron can easily be separated from Gangue by this method Large amount of ore can be purified by this method It has two rollers one is magnetic roller other one is nonmagnetic roller When ore is dropped on the magnetic roller it moves through conveyers and it flows from the magnetic roller

Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility as a rule 20– 90·107 m3kg8

The inclusion of medium intensity magnetic drum separation MIMS in combination with jigging may be considered for the beneficiation of the 61mm fraction of some friable ore bodies The following diagram demonstrates some typical flowsheet designs for Iron Ore beneficiation of hard rock and friable ores
