A copper-lead-zinc polymetallic sulfide ore, being characterized by complex dissemination of main minerals and intimate intergrowth of valuable minerals and gangue, was taken for study. In an experiment, the raw ore grading 0.21% Cu, 2.37% Pb and 3.01% Zn was treated with a weak-alkali process, consisting of Cu-Pb bulk flotation, Cu/Pb separation and Zn flotation. With A22 as a copper-lead bulk flotation collector, TZ01 and zinc sulphate as depressants of zinc and sulfur minerals, CZ08 as a zinc flotation collector, sodium sulfite and CMC as depressants for Cu/Pb separation, a copper concentrate grading 22.09% Cu at 70.48% recovery, a lead concentrate grading 59.48% Pb at 89.35% recovery, and a zinc concentrate grading 45.00% Zn at 86.96% recovery were yielded.

针对某铜铅锌多金属硫化矿主要矿物嵌布关系较复杂、有价矿物与脉石共生关系密切的特点，在原矿铜品位0.21%、铅品位2.37%、锌品位3.01%条件下，采用铜铅混合浮选-铜铅分离-锌浮选的弱碱工艺流程，以A22为铜铅混合浮选捕收剂，TZ01+硫酸锌为锌、硫矿物抑制剂，CZ08为锌浮选捕收剂，亚硫酸钠+CMC为铜铅分离抑制剂，最终获得了Cu品位22.09%、回收率70.48%的铜精矿，Pb品位59.48%、回收率89.35%的铅精矿和Zn品位45.00%、回收率86.96%的锌精矿。
