Magnetic separation technology is a physical separation method that uses the differences in magnetism between matter to separate them from each other by different motion behaviors in a non-uniform magnetic field. It is highly efficient, green, and environmentally friendly, with little change in the physical and chemical properties of raw …

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 …

In another study, Ezhov and Shvaljov (2015) used a laboratory-scale EVS-10/5 magnetic separator for dry beneficiation of iron ore of the Backer deposit. This was done by analysing the influence of the current strength in the electromagnet winding of the magnetic separator on concentrate yield and recovery.
