    In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from theirinterlocked state physically by comminution. As a rule, comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral.
