    IntroductionOre ClassificationComminution ProcessesProcess SelectionMill SizingConclusionReferencesComminution is the process where ore particles are liberated from gangue material through progressive size reduction in the form of crushing, grinding, cutting or vibrating. The costs associated with power supply, grinding media, and liners used in comminution circuits almost always represent the single largest cost in gold extraction processes (Mosher, 2005). Thus, the efficiency of the entire processing operation is largely dependent on the efficiency of the comminution circuit. Sufficient comminution can be accomp
