Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the proce

The goal of comminution is to crush the ore into small particles that contain only one mineral. Dry crushing ore to ~1-5 mm particles is carried out on crude ore by compression and impact force. Jaw, cone, hammer, roll, and gyratory crushers are the tools used to do this.

In the primary stage, the devices used are mostly jaw crushers with openings as wide as two metres. These crush the ore to less than 150 millimetres, which is a suitable size to serve as feed for the secondary crushing stage. In this stage, the ore is crushed in cone crushers to less than 10 to 15 millimetres.

There is an increasing tendency to use an extra stage of crushing instead of a rod mill because crushers are more energy efficient. Wet ball mills are usually operated in closed circuit to control the product size distribution. At these fine sizes, only classifiers have sufficiently high capacities.
