In this paper, the mineral processing research has been carried out for solving production problems of Xiaomaoshan Copper-lead -zinc Mine. A novel processing technology has been developed to recover copper and lead by bulk-flotation and separation, followed by zinc-flotation. For the separation of copper and lead ,a new nontoxic depressant THB-2 has been used, which has the advantage of eliminating conventional dewatering and reagent removal process. The goal of Cu/Pb/Zn -separation for the Xiaomaoshan multi-metallic ore has been achieved and this process has now been successfully applied to the industrial production. The technology for the bulk-flotation and separation of copper and lead has the flow structure to be simple, compatible, the separation efficiency high characteristic and opened new avenues of Cu-Pb separation in China.%试验采用铜铅混选分离一再选锌工艺流程,应用新型无毒铜铅分离药剂THB-2,无需传统铜铅分离脱水脱药工序,实现了小茅山铜铅锌矿多金属矿石的选矿分离,并成功应用于工业生产.该工艺使用无毒环保的铜铅分选药剂,具有流程结构简单、适应性强、分选效率高的特点,为我国铜铅混选分离提供了新途径.
