Selectivity is a severe problem in dry magnetic separation. Dry rotating-disk magnetic separator utilizes radial magnetic forces that compete against centrifugal mass forces. Genuine equilibrium of forces, which is compulsory for high selectivity can thus be achieved at a high level of magnetic force. The potential of an iron-pole separator for intergrown ferromagnetics, as well as of a superconducting system for paramagnetic materials is discussed.
