Gold not only grinds six to twenty times slower than most minerals, it can even flatten and report to coarser size 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.
In essence, the circuit will reach an equilibrium product for a given ore type, grinding power and feed rate.The operator or control system can then focus on adjusting the new ore feed rate, mill density etc to achieve the desired grind, therefore always maximising throughput at the target grind for the ore characteristics and available power.
