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 .
