摘要
研究了稀土萃取过程中经常存在的Fe、Si、Al杂质对环烷酸萃取提纯钇工艺中乳化形成的影响,发现杂质Si对萃取过程的乳化影响较大。提出了料液的不同除杂方法,其中氧化吸附沉淀法能除去料液中的大部分Si,从而可消除萃取过程中的乳化现象。
The effects of non-rare earths impurities,such as Fe,Si,Al on the formation of emulsion phase were studied in the extraction of yttrium with naphthenic acid,and Si was found to be most significant one.Different solutions for removing the feed solutions were provided and an oxidation absorption precipitation method was proven to be the most effective approach,which can remove the emulsion phase in the extraction of rare earths.
