Comminution Mining Technology InfoMine

Blasting can be described as the first stage of comminution carried out in the mine site in order to remove ores from their natural beds. Comminution in the mineral processing plant takes place in a sequence of crushing and grinding processes. Crushing reduces the particle size of run of mine ore to such a level that.

crushing and grinding information Mine Engineer.Com provides .

This section is devoted to giving a very brief idea how mines crush and grind the ores (rocks) to obtain fine enough material to recover the valuable metals or minerals. In some cases, like aggregate, they merely need to crush to a certain particle size range and it is ready to use. The purple buttons at left are links to pages on.
