| Abstract: | This paper has searched refreshing of aging P 507 extractant by agent R 12 ,and also discussed the effect of R 12 consumption and reaction time on the absorption spectrum,extracting rare earth phase-separating time,and P 507 recovery of refreshed P 507 extractant.This method was successful in industrial production.The test and production results showed that there was no obvious difference and change between refreshed P 507 extractant and new P 507 extractant in extracting rare earth.This technique was simple,convenient,cheap,useful and reliable. |
