Gravity Recovery of Gold From Within Grinding Circuits

Gravity recovery of gold from within grinding circuits has become common in many operations around the world. Effective gravity concentration effort is a function of numerous factors including the quantity and size distribution of the Gravity-Recoverable-Gold (GRG) present, downstream processes, water balance and gravity section operating costs.
