1988-4-1 1988-4-1 INTRODUCTION One of the primary roles of comminution in mineral beneficiation is the liberation of valuable minerals. The extent of liberation achieved during com- minution can play an important role in determining the final concentrate grades and recoveries obtainable in a mineral processing plant.

Potential energy savings in comminution by two-stage ...
1988-4-1 1988-4-1 Comminution normally consumes a very large amount of energy in any mineral processing plant. One of the areas that appears to enable an appreciable saving of energy is the classification step in a closed ball mill circuit. Hydrocyclones are the major method for closing comminution circuits but employ only a single stage of classification.
