    One of the basic operations in minerals processing is grinding of the ore to the point where valuable minerals are liberated from the host rock. Subsequent operations then separate the desirable minerals from the gangue or waste. The grinding balls form the major portion of the consumable costs, and can be as high as 40% to 45% of the total costs of communition.
