The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or
