Mineral Comminution and Separation Systems

4. Comminution System To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

Comminution | Centre for Minerals Research

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
