  • Optimizing Grinding and Regrinding Capacity in Mill Design

     · Optimizing Regrinding Capacity. The justification for including regrinding of a concentrate or middling in the design of any new copper flotation plant should be that a greater economic return (by any preferred economic criterion) will result thereby than is obtainable at any fineness of primary grind without regrinding.
