    the semiautogenous grinding (SAG) mill where water is added for grinding. Underflow from the SAG mill drops into a sump and mixes with discharge from the ball mills. The sump slurry is pumped to a bank of cyclones. The grinding cyclone overflow reports to the rougher flotation. The underflow stream is divided and conveyed to each of the ball ...
