Magnetic and Electrostatic Separation

In mineral processing, low intensity magnetic separation (LIMS) and high intensity magnetic separation (HIMS) are used or WHIMS when carried out wet. The magnetic field of LIMS is ∼1000 gauss using permanent magnets, while the high-intensity units require an electromagnet to reach the higher fields of up to 20,000 gauss 1.

Wet High Intensity Magnetic Separation

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.
