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.

However, the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media. In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100.
