用火法冶金过程从粗硫化物中生产铜时 ,不纯的铜阳极必须进行电解精炼预处理。在铜电解精炼时 ,各种杂质 ,如锑 ,从阳极带入电解液中。随着操作的继续进行 ,其浓度逐渐升高 ,并在铜阴极上沉淀。电解液纯化的常规流程存在若干缺陷 ,例如能耗高 ,释放有毒的砷化氢气体等。目前 , Impure copper anodes must be subjected to electrolytic refining pretreatment when pyroprocessing is used to produce copper from the crude sulphides. In the electrolytic refining of copper, various impurities, such as antimony, are brought into the electrolyte from the anode. As the operation continues, the concentration gradually increases and precipitates on the copper cathode. The conventional process of electrolyte purification has several drawbacks, such as high energy consumption and release of toxic arsine gas. Currently ,
