They are used where ever the slurry is "being separated by grind size, density, or mineral content. In this case it is particle size. 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.
