Abstract
A method for determining the efficiency of separation of a dense media separation process is disclosed including determining an apparent distance a particle must travel to be correctly beneficiated and calculation of an apparent velocity for correct beneficiation. Apparent velocity, cyclone geometry, and operating parameters are used to calculate a divergence value which indicates the efficiency of separation. Cyclone geometry and operating parameters may be selected for use in a dense media separation process by adjusting geometry and operating parameters in a manner to obtain desired efficiency.
