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.
