Predicting Gravity Separation Gold Recoveries Springerlink

May 01, 1995 A novel methodology for estimating gold recoveries in gravity-separation circuits is presented. The methodology makes use of a population-balance model. The model represents gold liberation, breakage and classification behavior and applies preconcentration and recovery-performance curves to gravity-recoverable gold. The derivation of the necessary parameters is explained and
