摘　　要：针对某铜铅锌多金属硫化矿原矿铜、铅品位较低,矿物共生关系复杂,易浮难分的特点,采用"铜铅混浮-浮锌"的简单工艺流程,铜铅混合粗选时使用亚硫酸钠+硫酸锌组合抑制剂、丁铵黑药+丁基黄药组合捕收剂,实验室小型闭路试验获得了铜铅混合精矿中铅品位21.67%,回收率75.68%,铜品位2.37%,回收率75.54%;锌精矿品位55.42%,回收率88.12%的选别指标,可有效实现铜铅锌的浮选回收。Due to the low-grade of Cu and Pb,the complicated symbiotic relation and the feature of easy to float yet hard to be separated of a certain Cu-Pb-Zn polymetallic sulphide ore,a flow-sheet consisting of Cu-Pb bulk flotation-Zinc flotation was selected. Na2 SO3＋ Zn SO4 combined depressant and ammonium dibutyl dithiophosphate ＋ butyl xanthate combined collector were used in bulk flotating copper and lead.In the experiments of the closed-circuit flow,a bulk concentrate with 21. 67% of lead and 2. 37% of copper can be obtained by a recovery of 75. 68% Pb and 75. 54% Cu,as well as the zinc concentrate with zinc grade of 55. 42% and recovery of 88. 12%. And satisfactory results can be obtained.
