| Abstract: | The mineralogy study of an intricate Pb-Zn-Fe ore shows that Zn-Fe has the characteristics of irregular dissemination size,close intergrowth which made them quite difficult to be separated.A flowsheet consists of Pb-Zn differential flotation,Fe recover from tailings of Pb-Zn flotation by magnetic separation and flotation was introduced,and for a run-of-mine ore with a Pb grade of 1.94%,Zn grade of 2.24% and TFe grade of 21.90%,Pb concentrate with Pb grade and recovery of 57.93% and 90.93%,Zn concentrate with Zn grade and recovery of 49.97% and 83.95%,Fe concentrate with Fe grade and recovery of 65.08% and 47.30%,respectively,were produced,and the comprehensive recovery of Pb,Zn,Fe minerals can thus be achieved. |
