WHIM is the short acronym for Wet High Intensity Magnetic Separation. At present, most U.S. iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet low-intensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to …
This study aimed at the investigation of the effect of colloidal magnetic particles on the magnetic separation of iron ore tailings (IOT).

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.
Magnetic separation methods are used to take the advantage of the difference in the magnetic properties for separating iron ore from the non-magnetic associated gangue materials. Magnetic separation can be conducted either in a dry or in a wet environment, although wet systems are more in use.
