Crushing is performed in several stages, reduction ratios are ranging from three to six in each stage. The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy. Therefore, the optimization of grinding operation is very important. Energy. Both crushing and grinding require energy to reduce the ore size.

This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required for physical separation or chemical extraction are returned to the crushing or the grinding circuit.
