Ball Mill Size For Gold

The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns 0.1 mm . The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 –

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)
