  • COMMINUTION: Liberation, Crushing, Grinding Robert Machowski

    Jul 1, 2015 In minerals processing most of the minerals are very finely disseminated or associated with the waste (or the "gangue") fraction of ore. These minerals must be liberated before actual separation occurs: • Comminution, is the process whereby the particle size of the ore is progressively reduced until the clean

    Comminution in the mineral processing plant takes place in a sequence of crushing and grinding processes. Crushing reduces the particle size of runofmine ore to such a level that grinding mill can further grind it until the mineral and gangue is substantially produced as separate particles.

    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. The crushing and grinding process will produce a range of particles with
