Ultra fine milling for the recovery of refractory gold

Refractory gold ores may be defined as those which yield low recoveries of gold when treated by the conventional grinding and cyanidation process.Ultra fine grinding of silver plant tailings of refractory,,Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching (i.e. 36% Ag extraction rate from the as-received tailings with d 80 of 100 μm, c.f. 84% extraction rate after ultra fine,The Leachox™ Refractory Gold Process,Leachox, Ultra fine grinding, Vasilkovskoye, Refractory, Imhoflot pneumatic flotation, Leaching, Oxidation .
