Magnetic Separation | SpringerLink
A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21, 22 ].

Heavy Media Separation Process
The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
