萃取法回收铜电解液中锑铋研究与实践

Extraction Recovery of Antimony Bismuth in Copper Electrolyte by Research and Practice

以铜电解液为研究对象,采用有机相组成(N1923+磺化煤油+异辛醇)的萃取体系,物质A酸性络合反萃体系对铜电解液中锑铋回收工艺进行研究,确定工艺参数,并将研究成果应用于工业生产,结果表明,锑铋萃取率分别达84.1%和98.1%,锑铋反萃率分别达95.7%和90.6%,且不造成铜损失,对电解工艺无不良影响。

This paper takes copper electrolyte as the research object, adopts the organic phase composition （N1923＋sulfonated kerosene ＋ isooctyl alcohol） extraction system. And it studys material A acid complexing extraction system of copper electrolyte in antimony＆ bismuth recovery process, determining the process parameters. The study results are applied to industrial production, which shows that antimony＆ bismuth extraction rate was 84.1% and 84.1% respectively, antimony＆ bismuth stripping rate were 95.7% and 95.7% respectively, with no copper loss and no adverse effect on electrolytic process.
