Abstract

Mixtures of particulate solids are separated by introducing them to a suspension of magnetic particles in liquid, the particles being of such size that they would tend to flocculate if exposed to a simple constant or alternating magnetic field, flocculation being inhibited by causing the particles to spin. A magnetic field may be applied to enhance the density of the fluid relative to the mixture, and different constituents of the mixture either float or sink and are separately collected. The spin may be imparted by a travelling or rotating magnetic field, which may also serve as the means for creating the enhanced relative density. The travelling field may be provided by a linear magnetic stator (6) with polyphase windings excited from a suitable AC supply (7). <IMAGE>
