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.

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can vary from 0.4 percent to ...

Beneficiation of copper ores produces concentrates consisting mostly of sulfide minerals, with small amounts of gangue oxides (Al2 O 3, CaO, MgO, and SiO 2 ). Theoretically, this material could be directly reacted to produce metallic Cu by oxidizing the sulfides to elemental copper and ferrous oxide: (5.1) (5.2) (5.3)

This allows immense cost savings for transport, since the waste rock is disposed of on-site. Additionally, higher prices can be achieved with the concentrate since the ore content is considerably greater. But larger plants, with integrated recovery facilities, also profit enormously from our ore sorting technology.

Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3-10m high, 10 4 -10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1-5kg Cum −3.
