When liberation problems are part of the ore's characteristics the designers of the concentrator plant will include a REGRIND MILL in the Basic Flotation Circuit Design of its flow sheet. A regrind mill is precisely that, a mill that grinds the material again after it has been concentrated at least once.

This method is likely to be less costly than one involving the fine grinding of the whole ore. No standard system can be given for handling the various products as their disposal depends so much on the occurrence of the minerals and the efficiency of the regrinding operations, but a typical flow sheet is illustrated in circuit No. 12 (Fig. 60).

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
