GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING

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).
