    Comminution is the most energy intensive process stage in the mining industry It uses at least 3% of the global electricity and, according to the Coalition for Energy Efficient Comminution, accounts on average for more than 50% of a mine’s energy consumption and 10% of the total production costsThe rising costs for and the possibility for limited availability of electrical energy are emphasizing the continual conflict faced in the selection of comminution circuits used in preparing ores for concentration, namely; capital cost vs operating cost Frequently, the circuit with the lowest capital cost is not the most efficient in the use of electrical power and wear resistant materialsCrushing & Grinding Circuit Design Comminution
