Permanent magnetic rolls have found wide area of applications in separation of paramagnetic minerals from diamagnetics especially after the development of neodymium-iron-boron magnets. Their simple separation principles together with relatively high magnetic induction values and relatively low capital and operational costs made them preferable in industrial minerals processing. Besides the magnetic field and induction values of the magnets, another important factor is the magnet-steel configuration where the magnet:steel width ratio is the key factor that should carefully be selected depending on the feed particle size. In this study, the effects of magnet-steel configurations on the removal of iron-bearing impurities from a feldspar sample are investigated.
