Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the proce

Comminution Multotec
Comminution. 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 ...

A liberation model for comminution based on probability theory
2004.4.1 A good introductory text for mineral processing is by Wills (1992). In order to increase liberation, particles need to be broken as fine as possible; however by decreasing particle size, energy costs substantially increase, and it becomes more difficult to separate particles.
