| 摘 要： | 采用沉淀法对浸铅液中的铅、铜有价元素进行了综合回收。对比研究了不同沉淀剂对铅、铜的沉淀效果，结果表明碳酸钠作为沉淀剂的效果较好。通过单因素实验考察了沉淀过程中温度、溶液pH、时间等因素对沉淀效果的影响，确定了最佳条件：调节溶液pH=6.0、常温反应60 min。在此条件下，采用碳酸钠沉淀剂进行沉淀反应，铅、铜沉淀率分别达到了99.99%、97.50%，有效实现了浸铅液中有价元素的分离回收。

| Abstract: | Comprehensive recovery of valuable elements lead and copper in the lead leaching solution was made by precipitation method.Sedimentation effects of different precipitants on Pb2+ and Cu2+ were comparatively studied.The results showed that sodium carbonate as a precipitating agent had the best effect；the effects of temperature，pH，and time on the sedimentation effect were investigated by single factor experiments.The optimum conditions were as follows：the solution pH was 6 and the reaction time was 60 min at normal temperature.Under the optimum conditions，the sedimentation rates of lead and copper reached 99.99% and 97.50%，respectively.Thus，the separation and recovery of valuable elements in the lead leaching solution was achieved effectively. |
