| Abstract: |
| A solvent extraction process using P204-kerosene system for separation vanadium from leaching solution bearing vanadium was studied.The relationship between saturation capacity of vanadium in organic phase and volume content of P204 was determined.And according to the extraction result of single condition,multistage countercurrent extraction and stripping were carried out,and the conclusion was drawn that at least 6~7-stage countercurrent extraction was carried in roder to achieved over 95% extraction rate ... |
