摘　　要：本文对某湿法提铜萃余液采用除铁-硫化-深度中和处理工艺处理,可以实现萃余液中铜、锌综合回收,铜、锌总回收率分别达76.45%和80.03%,深度处理后的铜离子浓度均<0.5 mg/L,可达到排放标准,实现萃余液的资源化和无害化处理。In this paper,iron removal-sulfurization-deep neutralization process was used to treat the raffinate of copper hydrometallurgy.which can realize comprehensive recovery of copper and zinc in the raffinate.The total recovery of copper and zinc reached 76.45% and 80.03% respectively,the copper ion concentrations after deep treatment were all less than 0.5 mg/L,which can reach discharge standards and realize the resource recovery and harmless treatment of the Raffinate.
