| 中文摘要 |
| 研究从含AU、Ag和Pb废料中综合回收AU、Ag和Pb的电化学分离过程。在实验确定的最佳工艺条件(电极组成:70g/LPb2+、100g/L ∑(SiF62-).电解温度40℃,电流密度100A/m2,β-萘酚、骨胶浓度分别为0.002g/L和0.5g/L)下制得了纯度为99%Ph的平滑致密阴极铅沉淀物,铅电流效率大于98%,比电能消耗117kw·h/tPb,AU、Ag进入阳极泥的回收率分别高于99%和98%。 |

| The electrochemical separation process for comprehensive recovery of gold,silver and lead from An, Ag-containing,scrap was investigated. The smooth and dense cathayic deposit with purity of 99% Ph was prepared by electrochemical separation process under the optimal technological conditions(electrolyte compoSiwhl 70g/L Pb2+,100 g/L total SiF62- solution teoprature:40℃.current densityl 100 A/m2;concentration of β-naphthol tobone glue: 0.002 g/L and 0.5 g/L)experimentlly.The current efficiency of lead was higher than 98%,the speCific electric energy consumption was 117 kW·h/tpb. The recovery of Au and Ag in the anode slime were as high as 99% and 98% respectively. |
