摘　　要：根据某高硫难选铅锌矿石的原矿性质,进行了浮选药剂条件试验和闭路试验研究。采用石灰调浆、硫酸锌抑制锌矿物,混合捕收剂优先浮选铅,在低碱条件下,用新型活化剂X-41活化选铅尾矿,丁黄药选锌,可以实现铅、锌的高效分离,铅精矿铅品位和回收率分别达到60.32%和77.03%,锌含量为7.51%;锌精矿锌品位40.27%、回收率78.13%,铅含量2.47%。According to the property of a refractory lead -zinc ore with high pyrite, experimental study had been conducted on reagent conditions of floatation and closed - circuit tests for compre- hensive recovering all kinds of useful minerals. A flotaion flowsheet was put forward, which consists of preferential flotation of lead minerals with CaO as regulator, ZnSO4 as zinc depressant, mixed reagent as collectors, and zinc flotation from the lead tailing using X -41 as activator and butyl xanthate as collector under the condition of low alkali. Using this process, the lead concentrate was successfully separated from the zinc concentrate, and the lead concentrate of 60.32% Pb with a recovery of 77.03% and zinc content of 7.51% and the zinc concentrate of 40.27% Zn with a recovery 78.13% and lead content of 2.47% were obtained.
