| Abstract: |
| High-grade copper-bearing gold concentrate was treated by processes of fluidized sulfating roasting, acid leaching, and cyaniding leaching. The industrial practice shows that copper total recovery rate is 97%, copper in acid leaching slag is below 0.3%, gold and silver cyaniding leaching rate is 96.84% and 75.45%, the average total conversion rate of SO2 is 98.74%, and SO2 concentration in waste gas is 0.061% when the gold concentrate bearing 7%~10% copper is treated by the above processes. |
