The cyclone underflow is directed to the ball mill- for further grinding. Once the ore has passed through this mill it will be added back into the material that is being pumped to the cyclone for reclassification. The hydrocyclone product is the overflow, which of course is finely ground rock. It is this overflow which must be controlled.

The aim of the ball millcyclone circuit is to produce the optimum flotation feed particle size while maintaining grind throughput. The optimal operating point is a tradeoff between throughput, recovery and grinding cost. Copperton recently focused on the role of the cyclone battery and how to monitor the performance of each individual cyclone.
