Beneficiation of South African chromite tailings using magnetic separation

There are proven and well established widely accepted techniques for concentration of chromite ores such as spiral concentration, jigs and shaking tables. However, these techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75μm) resulting in this size fraction lost to the tailings.
