| 摘 要： | 贵溪冶炼厂从铜电解过程产出的阳极泥中进行金银贵金属和硒碲等稀散金属的回收,近年来随着生产规模的扩大,原料成份也有变化,碲回收系统中锡含量上升,对生产造成不利影响.通过提高碲电解废液的氢氧化钠浓度,对生产系统中的锡进行分离,结果显示,碲新液和电解液中锡含量从40g/L降至10 ～ 15g/L.

| Abstract: | Gold, silver, selenium, tellurium and other precious metals were recovered from anode slime during copper electrolysis process in Guixi smelter. As the production expansion in recent years, material＇s component also changed; high stannum content in tel-lurium recovery gave harmful influence to production operation. Through increasing sodium hydroxide concentration, stannum was sepa- rated from operation system. The result showed the stannum content in new tellurium solution and electrolyte solution decreased from 40g/L to 10 - 15g/L. |
