In some ores a large percentage of the gold occurs with the sulphides, which may only constitute a small proportion of the ore. Extremely fine grinding may be necessary to liberate this gold from the enclosing sulphides. In these cases, if the entire mill feed was entirely ground, the cost of the operation would be very high.

The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.
