### size reduction mineral liberation model

Feb 28, 2019 In describing the size reduction of a binary mineral system which is undergoing liberation, it is necessary to account for the fact that three types of particles are being broken, the two liberated mineral species and the locked specie. When liberated particles break to a finer size fraction, they remain liberated and of the same mineral specie

Jan 12, 2018 3.0 Liberation and Comminution. 3.1 Liberation. In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution
