| Abstract: |
| A combined process was investigated to separate and extracte valuable metals from calcine of polymetallic and complex gold concentrate by Cu and Zn recovery with acid leaching, Pb and Ag recovery with salt leaching, and gold recovery with cyanidation. Reasonable process parameters were determined. The results of combined tests show that recovery of Au, Ag, Cu, Zn, and Fe is 94.63%, 65.12%, 90.45%, 82.87%, 98.92% respectively under the optimum conditions. Comprehensive recovery of valuable metals is effectively realized. |
