WebIntroduction to Mineral Processing 5 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. WebMineral Liberation. Historically, mineral liberation has been used as a proxy for the “processability” of a particular mineral, since the many properties of minerals that could allow for concentration and processing could not be directly measured from auto-SEM instrumentation.
