Effect of Various Variables on Gravity Gold Recovery in Grinding Circuits - Results from Mathematical Modeling (KC-ModPro)
December 4th, 2001
An interative model was developed to further understand the factors affecting gravity gold recovery (GRG) within a grinding circuit. Input variables for the model are; the gravity-recoverable-gold (GRG) content of the ore, the fraction of the cyclone underflow (circulating load) treated using a gravity recovery unit, the stage recovery of the gravity concentrator, the probability of a GRG particle reporting to the cyclone underflow (survival to cyclone underflow) and the probability of a GRG particle surviving as gravity recoverable in the grinding mill.
