An experimental research was carried out on mineral processing of a skarn-type low-grade copper-lead-zinc polymetallic sulfide ore from the southwestern Yunnan under low-alkali conditions. In view of the ore characteristics, such as multiple valuable elements, fine dissemination and uneven distribution of useful minerals, a low-alkali processing technique consisting of copper-lead bulk flotation, Cu/Pb separation, and zinc flotation was proposed. With the combined reagents of Z200 and BK906 as the collector for copper-lead bulk flotation, a combination of zinc sulfate, sodium sulfite and sodium sulfide as the depressant, sodium sulfide combined with activated carbon as the reagent removers for copper-lead concentrate, BK902 as the lead collector and BK520 as the copper depressant in the Cu/Pb separation, copper sulfate as the activator in zinc flotation and BK906 as the zinc collector, a closed-circuit test produced a copper concentrate grading 24.05% Cu at 88.18% recovery, containing 2.54% Pb and 188.00 g/t Ag, a lead concentrate grading 75.55% Pb at 81.08% recovery, containing 2.57% Cu and 1 410.00 g/t Ag, and a zinc concentrate grading 52.21% Zn at 90.47% recovery, respectively.

对滇西南某矽卡岩型低品位铜铅锌多金属硫化矿开展了低碱条件下的选矿试验研究。针对该矿石有价元素多、有用矿物嵌布粒度细且分布不均的矿石特性，提出了低碱条件下的铜铅混合浮选-铜铅分离-锌浮选工艺流程，以Z200+BK906为铜铅混合浮选捕收剂，硫酸锌+亚硫酸钠+硫化钠为锌矿物抑制剂，硫化钠和活性炭为铜铅混合精矿脱药剂，BK902为铜铅分离铅捕收剂，BK520为铜铅分离铜抑制剂，硫酸铜为锌浮选活化剂，BK906为锌捕收剂，闭路试验获得了铜品位24.05%、铜回收率88.18%、含铅2.54%、含银188.00 g/t的铜精矿，铅品位75.55%、铅回收率81.08%、含铜2.57%、含银1 410.00 g/t的铅精矿和锌品位52.21%、锌回收率90.47%的锌精矿。
