摘　　要：介绍了株洲冶炼厂铟富集的生产情况 ,提出了存在的问题。就如何改进生产工艺 ,以提高铟渣品位及铟回收率作了较深入地探讨。对比了工艺改进前后的生产效率 ,结果表明 :工艺改进后铟渣品位和铟回收率均得到较大的提高 ,铟渣品位由 1 995年的 2 .2 3 %提高到 2 0 0 1年的 4.1 1 % ;铟回收率由 1 995年的 41 .64 %提高到 2 0 0 1年的 62 .49%。A description is made of the present situation and existing proble ms of indium enrichment of Zhuzhou Smelter. A further discussion is made of how to improve the technology to increase indium residue's grade and indium recovery . Compared with the original technology, it is shown that the new indium enrichm ent technology can improve greatly the grade of indium residue and the indium re covery, that is to say, the former increases from 2.23% in 1995 to 4.11% in 2001 and the latter from 41.64% in 1995 to 62.49% in 2001. New suggestions are made for the high acid indium-leaching technology.
