    摘要
  • 摘要: 研究了用萃取法直接從包頭硫酸浸出液中分離稀土與鐵,稀土的回收率達到99%以上;分離后的溶液Fe(Ⅲ)<0.011g/l,避免了用沉淀法除鐵時,由于稀土共沉而損失10%的稀土。同時還提出了萃合物的組成。

     

    Abstract: The technological process of separating Fe(Ⅲ) from rare-earth sulphate leaching selection originated in Baotou rare-earth mine with solvent extraction method has been obtained. The rate of recovery of rare-earth is more then 99%. The content of Fe(Ⅲ) is less than 0.11g/l in the solution after being separated. The 10% loss of rareearth which is resulted from coprecipitation of rare-earth with Fe(Ⅲ) in the process of separatiag femc ion with sediment method is avoided. The composition of extracted complex determined as well.
