    Rare Earth Magnetic Roll Separators Mineral is fed as a layer onto a thin belt (0.5 millimetres) that carries the feed to a magnetic roll. The magnetic roll consists of alternate slices of rare earth magnet and mild steel. The rare earth produces a magnetic field that converges (is strongest) at the mild steel slices.
