(1) Crushing and Grinding of the Ore. The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders. These pieces are then reduced to fine powder with the help of a ball mill or stamp mill. This process is called pulverisation. (2) Concentration of Ore or Ore Benefaction
The copper ore processed into granules is screened by a vibrating sieve and sent to a ball mill for grinding and crushing. Here also need to use auxiliary equipment a classifier, which can classify and screen the copper ore and release the copper ore powder that meets the requirements.
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 ...
