| Abstract: |
| The valuable minerals in tailings from Yunnan Province are mainly minerals bearing-Ag, the grade of Ag is 85.47g/t, other minerals are Pb and S, the grade is individually 0.62% and 1.75%. The different recovery processes for Ag are completed and results indicated that flotation processes is prefer to gravity. A preferable closed-circuit result was obtained by once roughing,two scavengings and three cleanings. The grade of Ag and Pb in concentrate is respectively 137.09g/t and 5.85%, the recovery of are individually 55.27% and 60.35%. The reutlization of tailing resources was achieved by the recovery of Ag and Pb. |
