| Abstract: | In this paper mineral of Pb,Zn,S and gangue was fine-disseminated in crude ore,degree of Pb was 1.20%,degree of Zn was 7.54%,degree of S was 20.96%,was a refractory lead-zinc mine.At the same time the reasonable effective flotation process flowsheet and medicament were adopted to obtain better index:concentrate of Zn degree was 61.53% and recovery was 69.67%;concentrate of Zn degree was 52.24% and recovery was 89.84%. |
