Cyanidation during Grinding 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.
