Energy efficient Comminution circuits

Energy efficient comminution circuits Mining processes require heavy capital investments and generates high operational costs which are mainly due to high energy consumptions. Of all the mining processes, grinding circuits are the most energy intensive component consuming up to 10 times more than crushing and 100 times more than blasting.
