Beneficiation of an iron ore fines by magnetization
2017-11-10 The beneficiation of a hematite ore fines with magnetization roasting and magnetic separation was proposed and studied. The magnetic properties of ore can be enhanced due to the selective conversion of hematite and siderite into magnetite. Magnetization roasting can be applied effectively for the processing of carbonate-containing hematite ore.

Developments in the physical separation of iron ore:
2015-1-1 Oxidized iron ores are much more difficult to upgrade by magnetic separators, because their magnetic susceptibilities are only about 1% or less of that of magnetite. In oxidized iron ore separation, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries. 9.3.2.1.
