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.
Copper and gold are recovered from the ore using traditional grinding and flotation methods in the concentrator. The plant has a current processing rate of ~6.8Mtpa (8.5Mtpa capacity and scalable to ~11Mtpa). The concentrator incorporates grinding (four mills), conventional flotation and dewatering. A single copper-gold-silver concentrate is
