fractions. The long residence time of the gold within the grinding circuit can cause some of the GRG to become non-gravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).Therefore, to add appropriate water to wet ball mill can improve the efficiency of the wet ball mill by avoiding too dry ore processing. 2. Change the size of the grinding media The wet ball mill's grinding media diameter is one of the factors that affect the efficiency of the mill.
