what is comminution in mineral processing

Aug 11, 2019· Comminution in mineral processing refers tocrushing and grinding operations. It’s a size reduction process that consists of breaking the mined ore into small pieces. The product of comminution could be fine size particles or coarse grains depending on two things; the size liberation of valuable minerals from gangue and the further separation process.

    In mineral processing, the liberation refers to the unlock of minerals ore assembly, which means making minerals or some minerals free. It is also known as the release of valuable minerals from the gangue. The prupose of liberation in minerallurgy is achieved through progressivecomminution, besides sizing and classification control processes.
