principles of mineral processing mining and crushing

Mineral Processing - SlideShare

The mineral beneficiation involves separation of gangue minerals from ore. It has three steps Liberation, Separation, Concentration. 1) Liberation of valuable mineral by size reduction. 2) Separation of coarse and fine particles. 3) Concentration to separate the gangue minerals to increase the metal grade.

Comminution | Multotec

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer ...
