研究了以新型萃取剂Cyanex272为载体乳状液膜富集稀土的最优膜配方和工艺条件，考察了从南方离子型稀土矿实际浸矿液中富集稀土的情况，进行了混合载体的筛选等，结果表明：以Cyanex272为载体乳状液膜能有效地富集稀土，对于实际料液，其迁移率大于98％．富集液中稀土浓度达90g／L．所得RE_2O_3产品稀土总量大于97％． The optimal membrane formulation and process conditions for enrichment of rare earths with Cyanex272 as carrier were studied. The enrichment of rare earth from the actual leaching solution from southern ionic rare earths was investigated, and the selection of mixed supports The results show that the emulsion with Cyanex272 as the carrier can effectively enrich the rare earths, and the mobility is more than 98% for the actual liquid. Rare earth concentration of the enrichment of 90g / L. The RE RE-O 3 RE product is more than 97% in total.
