摘　　要：针对环烷酸萃取除铝传统方法存在的除铝效果差和易乳化的缺点,研究开发了一种高效、理想的除铝方法,采用单级HA萃取,除铝后料液铝含量可小于10 mg/L,稀土回收率大于90%,除铝成本低。This paper proposed a new technology for aluminum removal from rare earth feed liquid with naphthenic acid.The result showed that content of aluminum in the solution could be decreased to less than 10 mg/L by one-stage extraction,and rare earth recovery was more than 90%.The technology has lower cost.
