摘　　要：针对某地银铜铅多金属硫化矿易浮难分离、嵌布粒度不均匀的特点,采用优先选铜-铜浮选尾矿选铅的工艺流程,取得了较好的技术指标:铜精矿中铜和银品位分别为22.5%和55 253 g/t,回收率分别为63.75%和67.58%;铅精矿中铅和银品位分别为62.05%和5 045 g/t,回收率分别为80.46%和18.24%。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.
