Primary crushing brings run-of-mine ore down to a maximum size of the order 4 to 6 in average diameter secondary crushing receives feed at 6 and reduces it to below Dry crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called grinding.

Tumbling mills with either steel rods or balls, or sized ore as the grinding media, are used in the last stages of comminution. Grinding is usually performed wet to provide a slurry feed to the concentration process, although dry grinding has limited applications. The chapter also presents the simulation of comminution process and circuits.
