  • MATERIALS AND METALLURGY: Crushing and Grinding

    In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding). The particle size of the ore after its mining is progressively reduced until the free liberated particles of mineral can be separated.
