“B”试剂回收锗新工艺在我厂的应用及改进

Application and Upgrade of Ge Recovery Process Using B Reagent at Zhuzhou Smelter

介绍了“Ｂ”试剂回收锗新工艺在株洲冶炼厂生产应用情况。针对生产中出现的问题，对该工艺进行了改进研究。结果表明：将连续补加ＹＷ－１００改为间断补加ＹＷ－１００，可以使ＹＷ－１００的耗量降至连续外加的１／６～１／４，并减轻了萃取过程中的乳化现象；将反萃剂“Ｂ”试剂浓度由原工艺的２．０～２．３ｍｏｌ／Ｌ降至０．５～１．０ｍｏｌ／Ｌ，可以省去滤饼两次洗涤工序和蒸发工序，并解决了循环液体积膨胀需定期排放的污染环境问题，从而提高了锗的回收率和降低了“Ｂ”试剂的耗量。生产实践证明了上述结果。

Application and upgrade of Ge recovery process using Breagent are presented. Practice shows that discontinuous addition of YW-100, instead of continuous, can lowered the YW-100 consumption to1/6-1/4 and reduced the emulsion during solvent extraction The use ofback extractant (B reagent) concentration of 0.5-1 .0 mol/L, instead offormer 2.0-2 .3 mol/L, can eliminated the two-stage cake scrubbing andevaporization operations, thus the environmental problem arising fromthe need for regular discharge of the excessive circulating solution hasbeen solved, Ge recovery is improved and consumption of B reagent isreduced.
