Effect of pH on Copper Cleaner Flotation (after Regrind Circuit)

Effect of pH on Copper Cleaner Flotation (after Regrind Circuit) The secondary copper mineral grain size is moderately finer, averaging 17 µm, and requires a finer regrind. This ore type is processed early in the mine plan and therefore a target of 25 µm was selected for the basis of the regrind design.
