Oxygenated Leaching of Copper Sulfide Mineral under Microwave-Hydrothermal Conditions


A study on microwave assisted chalcocite leaching was carried out with a microwave hydrothermal reactor. The leaching was conducted with thick mineral slurries (50-100g/l). The leaching media is a mixed solution of CuCl2 and NaCl. The investigation included the effect of leaching temperature, quantities of the minerals per unit slurry volume as well as the initial concentration of cupric ions. The results were discussed and compared with using conventional leaching method.
