从冶炼烟尘中回收铟的产业化技术研究

Study on industrial technology of recovering indium from smelting dust

本文针对冶炼烟尘中含砷氟氯较高,在回收铟时产生的砷化氢气体会造成人身中毒,废水中含氟氯离子高,不能将含Zn液体返回电锌系统回收利用等问题,寻找从浸出液中分离Zn、In、As、F、Cl的工艺方法,并开发工业化应用技术。

In view of problems such as the high content of fluorine, chlorine and arsenic generated in smelting dust, the arsine in the process of indium recovery are poisonous to people, the content of fluorine and chlorine iron in waste water is high, and the liquid containing Zn cannot back to zinc electrolysis system to recycle etc, the process of separating Zn, In, As, F and C1 from leaching liquid was studied, and the industrial application technol- ogy was developed.
