Gravity recovery of gold from within grinding circuits
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).

SAG vs. AG Mills: Understanding the Key Differences
For instance, in a study conducted on a copper-gold orebody, it was found that the power consumption of an AG mill is 25% to 30% lower than that of a SAG mill for the same capacity. Lower power consumption in AG mills can result in significant cost savings, making them a preferred choice in many mining operations.
