贵州铁路锌厂锌浸出液中含有４０～５０ｍｇ／ＬＧｅ。采用本研究的萃取法从这种浸出液中分离回收锗的工业生产仅处理浸出液约７０ｍ~３）实践表明：经三级萃取、一级反萃取，锗的萃取率和反萃取率分别为 ９５％和９９％，粗 ＧｅＯ_２产品含锗３０％～４５％，萃取剂和反萃取剂均可循环使用，取得了比较理想的技术经济指标。 本文是该厂用本萃取法生产锗的实践总结。
Guizhou Railway Zinc Plant zinc leachate containing 40 ~ 50mg / LGe. The industrial production of separation and recovery of germanium from this leaching solution by this study only dealt with about 70m ~ 3 of leaching solution. Practice shows that after three-stage extraction, the first-stage extraction, germanium extraction rate and back extraction rate are 95% And 99%, crude GeO 2 products containing 30% ~ 45% germanium, extractant and stripping agent can be recycled, and achieved relatively ideal technical and economic indicators. This article is a summary of the practice of this plant for the production of germanium by this extraction method.
