MATERIALS AND METALLURGY: Crushing and Grinding

Mar 22, 2013 · Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding).

About this site

Crushing and grinding operations are employed to fracture mineral aggregates, and thus to increase liberation. The choice of fineness of grinding is an important decision as the ore must be sufficiently finely ground to liberate the valuable minerals. The accurate determination of grain liberation during reduction has a significant impact
