| Abstract: | Beneficiation technique for some complex polymetallic ore containing valuable components such as Cu, Ag, Pb and Zn was studied. A preferential flotation flowsheet was used, including sequentially a Cu-Pb bulk flotation and a preferential separation of copper by depressing lead, with the silver minerals enriched into copper concentrate. With the run-of-mine ore containing 0.58% Cu and 163.82 g/t Ag, the final copper concentrate was obtained at grade of 17.05% Cu and 5 623.6 g/t Ag, with recoveries of 77.62% Cu and 90.25% Ag, realizing an efficient recovery of copper and silver. |
