To achieve the goal of recovering these concentrates, the raw ore must be reduced to fine size prior to separation. This process is called ‘comminution’ or ‘size reduction’. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is ‘liberation’.
