Even though the magnetic field gradient in the separation zone can be as high as approximately 300 T m −1 at the surface of the magnet columns, it decays to 0 T m −1 at the middle of the separation zone. This phenomenon has caused the average magnetic field gradient within the separation zone to be approximately 90 T m −1 (table 1).

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].
