摘要： 对国外某铜铅银钡多金属矿进行铜铅混合浮选、抑铅浮铜、浸出、重选等实验研究，最终确定采用铜铅混浮?精矿浸出?尾矿重选的选冶联合工艺流程，实现了铜、铅、银、钡资源的综合回收. 结果表明，原矿含铜1.52%、铅7.84%和BaSO4 29.91%，银品位为243.8 g/t，经混合浮选得混合精矿含铜8.09%、铅47.21%、银1389.4 g/t，回收率分别为85.50%, 92.91%, 87.93%；在室温(25℃)、浸出剂浓度0.6 mol/L、液固质量比4、浸出时间50 min的条件下浸出，获得了铜、铅、银浸出率分别为84.95%, 5.56%, 21.04%的浸出液和含铜1.54%、铅64.23%、银1787.6 g/t的浸出渣. 浮选尾矿经摇床重选后得BaSO4品位为95.37%、回收率为35%的钡精矿.

Abstract: For one copper?lead?silver?barium polymetallic ore from abroad, the mixed flotation of copper?lead and the tests of depress lead?coppe float, leach and gravity were conducted, ultimately, the dressing-metallurgy combination craft of copper lead mixed flotation?concentrate leaching?tailings gravity was employed, and the comprehensive utilization of copper, lead, silver and barium was realized. The results showed that raw ores contained 1.52% of copper, 7.84% of lead, 29.91% of barium sulfate, and 243.8 g/t of silver. A mixed concentrate containing 8.09% of copper with copper recovery rate of 85.50%, 47.21% of lead with lead recovery rate of 92.91%, 1389.4 g/t of silver with silver recovery rate of 87.93% was obtained after the processing of mixed flotation. Mixed copper and lead concentrate were leached under the following conditions: the leaching agent concentration 0.6 mol/L at room temperature (25℃), the liquid?solid mass ratio 4 and the extraction time 50 min. The leaching rates were copper 84.95%, lead 5.56%, and silver 21.04%. Moreover, a containing 1.54% of copper, 64.23% of lead and 1787.6 g/t of silver was produced. Finally, gravity separation of tabling was conducted for the leaching residue and a concentrate containing 95.37% of BaSO4 with a recovery rate of 35% was obtained.
