| Abstract: |
| Based on the characteristics of mineralogy of Ag- pb- Zn ore at Wuxian Lead-zinc Mine,in consideration of the dificiency of existing mineral processing process,a regrinding stage is added to treat rougher lead concen-trate; higher selective composite collectors and combined depressants used in cyanide-free flotation; and the technological system of separation of Pb from Zn optimined. As a result, proper metallurgical performances from the impro-ved process flowsheet are obtained,solving the problem of producing poor concentrates containing considerable impurities; then improving the quality of concentrates; achieving better comprehensive utilization of Ag-Pb-Zn ore reserves. Wuxian silver-lead- zinc Mine has gained remarkable economic benefits. |
