Silver recovery. The section on processing silver ores also had to go. This noted that Hochschild's Ares mine is expanding the size of its plant and has ordered five additional …
The extraction of gold from refractory gold ores (RGOs) without side reactions is an extremely promising endeavor. However, most RGOs contain large amounts of sulfide, such as pyrite. Thus, investigation of the influence of sulfide on the gold leaching process is important to maximize the utilization of RGOs. In this work, the effects of pyrite on the …
