    Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is ‘liberation’. Liberation is the process to unlock composite minerals in the raw ore into more independent particles, and without it we cannot collect the wanted components only. The second objective of comminution in mineral processing is to adjust the size of mineral particles to adapt to
