MATERIALS AND METALLURGY: Crushing and Grinding

 · 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).
