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 circuits for gold ore processing ScienceDirect

01/01/2005· As the first step in comminution, drilling and blasting should be viewed holistically with the rest of the process. The obvious focus area is to minimize the overall cost of drilling, blasting, crushing, and grinding. The best approach, however, is not total comminution cost minimization, but overall revenue maximization.

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.
