| Abstract: |
| Valuable metals were recovered from copper bearing refractory gold concentrate by processes of batching, roasting, acid leaching, and cyaniding. The leaching rate of copper, gold, and silver is 95.15%, 98.18%, and 65.20% respectively. The special batching technology of gold concentrate based on laboratory investigation significantly improves copper leaching rate and comprehensive economic benefits of valuable elements after engineering application. |
