摘要:铟主要是从铅锌冶炼的副产品中提取。60年代,人们就用溶剂萃取法分离和提纯铟。生产采用浸出-萃取回收工序,但总回收率不高。因此,要提高铟总回收率,除对浸出工艺进行改进外,从萃取工艺上寻找更好的箱式水平萃取条件,提高铟的萃取率,是提高总回收率的途径之一。

   在设计中,老师给定了条件,选择对萃取相的改进,作了物料平衡,水系平衡,萃取箱的设计与计算,以及设备的选择根据实际需要及可能性,对车间做了布置,取其优点。尽量采用先进设备、结构、材料及新工艺。做到技术上先进,经济上合理,又减少环境污染。

ABSTRACT:Indium byproduct of mainly from zinc smelting extract. In the 1960s, people PNP solvent extraction separation and purification of indium. Production adopts leaching - extraction recovery work, but total recovery is not high. Therefore, to improve indium total recovery, in addition to leaching process improvement from the outside, seeking better extract craft level extraction conditions, enhances crate indium is to increase extraction ratio of total recovery of one of the path. 

   In the design, the teacher given conditions of extraction phase, choose the material balance, improve water balance, extraction box design and calculation, and the equipment choice according to the actual need and possibility, as far as possible, with advanced equipment. Structure. Materials and new technology. Be technologically advanced and economically rational, reduce the pollution of the environment.
