摘　　要：本文针对某复杂难选铅锑锌矿石,采用硫酸锌与亚硫酸钠组合抑制剂的无氰铅锌分离工艺,并使用新型有机抑制剂Q-Zn进行锌硫分离,小型闭路试验获得的铅锑精矿含Pb 25.32%、Sb 21.52%,铅回收率40.39%、锑回收率62.96%;锌精矿含Zn 44.81%,回收率79.00%;硫精矿含S 32.28%,回收率为49.13%。A combination of zinc sulfate and sodium sulfite cyanide-free process and novel organic inhibitors Q-Zn were used to separate lead-zinc minerals from the complex refractory lead,zinc and antimony ore.From the results of closed-circuit test a Pb-Sb concentrate with Pb grade of 25. 32% and Pb recovery of 40. 39%,antimony grade of21. 52%and Sb recovery of 62. 69%;,and a Zn concentrate with Zn grade of 44. 81%,and Zn recovery 79. 00%;sulfur grade of 32. 28%,and S recovery of 49. 13%,were obtained.
