    Comminution: Comminution utilises energy to reduce the size of ore particles in order to liberate embedded mineral grains so that they can be recovered in the subsequent process stages. The research under this theme focusses on understanding how energy is used in devices that use different breakage mechanisms to achieve size reduction and how energy is utilised in different comminution circuit

    Copper Ore Crushing The crushing section consists of three-stage ore reduction with either a grizzly or vibrating screen between each crushing stage. Removing fines before putting the ore through a crusher increases the efficiency of the crusher as it is then only working on material that must be reduced, and is not hampered by fines already reduced in size.
