| Abstract: |
| In the investigation of the flowsheets of mineral processing process for comprehensive utilization of Au-Ag sulphide ore at Zhanggongling Concentrator, both the technical and economical benefits were considered. In technology, four process schemes, such as crude ore cyanide leaching, flotation -cyanide leaching of flotation concentrate, fractional bulk flotation and selective flotation, were put forward. The comparison of characteristics of all these flowsheet schemes were done. Based on the test results, the economic benefits for all these four flowsheets were estimated. finally, in comparison of technical and economical benefits among these four flowsheet schemes, it is reasonal to use the selective flotation for treatment of Zhanggongling Au-Ag sulphide ore. |
