来冶铟系统技改设计思路浅述

The Brief Introduction of the Techniques Reform of the Indium System in Laibin Smelter

介绍了来冶铟系统技改中用矾渣挥发、三段浸出、萃取提铟工艺替代原有的矾渣焙解、二段酸浸、萃取提铟工艺的设计思路,以实现投入少、改动小、收益大的目标。

This paper introduces the idea that laibin smelter will replace the prevenient technique of alum residue's roast?two stages acid leach and extraction to abstract indium with the new abstracts indium technology of alum residue's volatilization?three stages acid leach and extraction. This technique would realize the purpose of reduce investment?vary a little and increase profit.
