Comminution is the process of physically breaking run-of-mine ore in order to achieve the liberation of valuable minerals .from gangue. The process itself is very energy intensive and it is estimated that nearly two percent of the United States power consumption is related to comminution (Comminution and Energy Consumption, 1981). With this in
