The concentrate will …

Bornite (Cu5FeS4), covellite (CuS) and chalcocite (Cu2S) are important sources in the world, and many ore bodies also contain some malachite (CuCO3.Cu(OH)2), azurite (Cu3(CO3)2.Cu(OH)2), cuprite (Cu2O), tenorite (CuO) and native copper. The sulphides, which yield most of the copper produced throughout the world, generally occupy the …

The copper produced in Chile by this route reached up to 40% of the total production in 2009, although a progressive decrease is predicted to 10% in 2030 (Cochilco, 2019). The main leaching ...

Figure 5 shows that copper extraction increases when the acid concentration increases from 0.02 M to 0.5 M. A further increase in the acid concentration resulted

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...
