Comminution Circuits Mineral Processing

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 many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of bone fracture.

Comminution - an overview | ScienceDirect Topics

Comminution of rock to produce fragments with a particle size susceptible to movement by aeolian suspension, saltation, and traction is effected on a large scale by several mechanisms including glacial grinding, weathering (notably by crystal growth), and fluvial and aeolian abrasion of particles in transport (Smalley et al., 2014; Woronko and Pisarska-Jamrozy, 2015; Fig. 8.1).

Comminution in mineral processing - MINERALLURGy

Comminution in mineral processing refers to crushing and grinding operations. It’s a size reduction process that consists of breaking the ore into small pieces. The result pieces can be fine size particles or coarse grains depending on two things; the size liberation of valuable minerals from gangue and the further separation technology.

What is liberation in mineral processing - MINERALLURGy

The Liberation of valuable minerals from gangue 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 progressive comminution, besides sizing and classification control processes ...
