| Abstract: |
| Beryllium was extracted from the sulphuric acid leaching solution of complex low grade beryllium ore with solvent extraction method. The effecting factors on beryllium single stage extraction rate were researched. The results show that the optimal conditions were pH in aqueous phase of 2~2.5, concentration of beryllium in leaching solution of 1.5~2.5 g/L, volume fraction of P204 of 30%, extraction time of 20 min, and W/O=1. In this conditions, more than 98.50% beryllium is separated by four stage countercurrent extraction. |
