To improve the recovery of associated precious metal Ag from an overseas lead-zinc ore, mineral processing tests were carried out based on raw ore process mineralogy. The results show that silver mainly occurs as exposed silver sulfide and encapsulated silver in sulfides. A process consisting of decarbonization and lime-free lead flotation was adopted, with aniline dithiophosphate as a collector, and zinc depressant CB-1 and auxiliary zinc depressant W-1 added in the roughing of lead flotation. As a result, a lead concentrate grading 56.70% Pb, 8.93% Zn and 1 432.30 g/t Ag was obtained, with corresponding recoveries of 80.73%, 2.13% and 59.07%, respectively. It is concluded that compared with the original lime-based process, the recoveries of Pb and Ag can be increased by 2.80 and 4.83 percentage points respectively, while in the lead concentrate, Zn grade can be decreased by 1.30 percentage points and Ag grade up by 35.80 g/t.

为了提高国外某铅锌矿共伴生贵金属Ag的回收率，在原矿工艺矿物学研究基础上进行了选矿试验研究。结果表明，Ag主要以裸露硫化银、硫化物包裹银形式存在；采用脱碳、无石灰铅浮选工艺，以苯胺黑药为捕收剂，铅粗选阶段添加锌抑制剂CB-1、锌辅助抑制剂W-1，可以获得铅品位56.70%、锌品位8.93%、银品位1432.30 g/t，Pb、Zn、Ag回收率分别为80.73%、2.13%、59.07%的铅精矿。与原石灰工艺相比，Pb、Ag回收率分别提高了2.80、4.83百分点，铅精矿中Zn品位降低了1.30百分点，Ag品位提高了35.80 g/t。
