| Abstract: | Flotation tests were conducted to dress a Cu-Pb-Zn polymetallic sulfide ore from Inner Mongolia by using a flowsheet consisting of Cu-Pb bulk flotation, Cu/Pb separation and Zn flotation from tailings. As a result, the test with an optimal reagent system and with a grinding fineness of -0.074 mm 80% produced a copper concentrate approaching 20.14% Cu grade at 40.27% recovery, a lead concentrate at 62.46% Pb grade at 93.56% recovery and a zinc concentrate at 48.84% Zn grade at 89.27% recovery, with the total silver recovery attaining 88.01%. |
