A method of separating lighter and heavier particles in a solids mixture includes entraining the mixture in a liquid of a specific gravity intermediate the specific gravities of the lighter and heavier particles. The liquid with entrained mixture is fed through a first opening into one end of a vessel and revolved therein by rotating the vessel. The vessel is designed so that the liquid attains a dynamic equilibrium at which an annular, centrifugally induced, substantially static revolving volume of the liquid of stable internal surface is confined by the vessel about the axis of revolution while further liquid flows on within the stable internal surface. The heavier particles are thereby …
