The process of crushing and grinding is referred to as "comminution" and is the most energyintensive stage of mineral processing. EXPLOITING DIFFERENCES After creating heterogeneity by liberating the valuable minerals from the waste rock, the next step is to separate these particles from one another by exploiting their differences.
