Abstract
To separate minerals, they are made up into a slurry A applied to a hollow tapered cylinder 301 spinning on its axis to generate 10 g centrifugal force. The cylinder 301 is also subjected to axial vibration at 5 to 10 Hz. The cylinder widens at a half-angle of 1.degree., and its axis is inclined at 2.degree. upwardly in the direction of widening. A film of slurry is held centrifugally to the internal surface of the cylinder and kept in suspension by the vibration. The denser (i.e. higher specific gravity) particles in the slurry tend to move preferentially radially outwardly (centrifugally) and to move downwardly in the boundary layer (under Earth's gravity). The action of the washing water B is to displace waste accidentally entrained with the higher-specific-gravity-particles. The valuable higher-specific-gravity particles overflow downwardly continuously at C and are collected. The washing water and lower-specific-gravity waste particles overflow upwardly over the top edge of the cylinder at C and are discarded.
