  • 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 nongravity 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).
