Magnetic fluid separation is a separation method that takes magnetic fluid as the separating medium and makes different minerals suspended in layers in the magnetoelectric field and gravity field in accordance with their magnetic intensity (or electric property contrast) and density under the action of an external magnetic field, …
Wet High Intensity Magnetic Separators (WHIMS) from Multotec apply magnetism, matrix rotation and gravity to achieve para-magnetic materials separation. Applications include heavy minerals, ilmenite, manganese and iron ore (haematite) beneficiation; PGM upgrading as well as manganese recovery from slimes dams.
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 …
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.
