Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.

Grinding is usually performed in a ball mill for the purpose of reducing the ore to sufficient fineness that the gold particles may be exposed to the dissolving action of the cyanide solution. This dissolving action may begin either in the ball mill or in the agitators. In the former case, the grinding is done in cyanide solution.
