| Abstract: |
| The dross of Zinc-smelt process have multiple valuable elements such as Ag、Au、Cu、Zn、Pb、Fe、C etc. According to the elements phase and disseminated features, the flotation process will be the appropriate methods to recycle the multi-elements. And then the coal concentrate contains 69.45%C.at a recovery of 90.03% with 6101 cal/kg heat. And the silver concentrate contains 1041g/t Ag、6.7g/t Au、3.1%Cu、9.0%Zn,Which at the recovery of 77.60%、65.93%、74.76%、53.68%. |
