| Abstract: | According to the properties of a certain Ag-Cu-Pb polymetallic sulphide ore, such as its good floatability and difficulty for separation, as well as an inhomogeneous distribution of dissemination size, a flowsheet of selective Cu/Pb flotation was adopted, resulting in copper concentrate graded 22.5% Cu and 55 253 g/t Ag with recoveries of 63.75% Cu and 67.58% Ag, and a lead concentrate graded 62.05% Pb and 5 045 g/t Ag with corresponding recoveries of 80.46% and 18.24%, respectively. |
