| Abstract: |
| Impurity separation and rare earth enrichment were conducted on the mother lixivium of ion-type rare earth ore by continuous adsorption and exchange technology based on heavy metal adsorption material. The results show that the rare earth concentration in desorption solution is above 100 g/L with the enrichment improved by about 200 times. The ratio of rare earth to aluminum and iron is 176.4∶1 and 568.3∶1 respectively. This process can simplify enrichment process of mother lixivium of ion-type rare earth ore, improve quality of concentrated rare earth solution and reduce cost. |
