Gravity Concentration of Gold-Bearing Ores and Processing …
The potential of any gold ore for gravity recovery is assessed using the standard gravity recoverable gold (GRG) test. This three-stage sequential process employs a 3-inch Knelson concentrator (KC-MD3) to evaluate the gravity recovery potential of gold ore (Laplante, Woodcock, and Huang Citation 2000). Typically, 50–100 kg of ore is used for ...
