中文摘要:

首席专家和铟被电解并且非恢复从铅的平衡溶剂萃取过程金条。电流密度,电解时期和铅和铟的电气化学的溶解上的电解质的圆数量的效果被调查。脱衣的装载器官的阶段上的铟的溶剂萃取上的抽取阶段比率和脱衣的阶段比率和脱衣的舞台的效果也被调查。试验性的结果显示在最佳条件下面,在阴极上扔的铅的纯净是98.5%,铅的存款率是99.9%,铟的溶解率是94.28%,铟的抽取率是98.69%,铟的脱衣的率是几乎100%,并且杂质元素 Fe 和 Sn 例如 Zn ,能被移开。

英文摘要:

Lead and indium were recovered by electrolysis and nonequilibrium solvent extraction process from lead bullion. The effects of current density, electrolytic period and circle arpJ ant of electrolyte on the electrochemical dissolution of lead and indium were investigated. The effects of extraction phase ratio and mixing time on solvent extraction of indium and striping phase ratio and stripping stage on the loaded organic phase stripping were also investigated. The experimental results indicate that under optimum conditions, the purity of lead deposited on cathode is 98.5% and the deposit rate of lead is 99.9%, the dissolution rate of indium is 94.28%, the extraction rate of indium is 98.69%, the stripping rate of indium is almost 100%, and the impurity elements, such as Zn, Fe and Sn can be removed.
