Process and apparatus for the recovery of uranium values from an organic extractant phase. |
摘要 |
<p>A process and apparatus are described for stripping uranium values from a uranium-loaded organic extractant phase containing, usually, a tertiary amine capable of forming organic-soluble uranium complexes. The sulphate-containing aqueous strip liquor is fed in co-current with the extractant phase to be stripped through a number of mixing stages in series connected one to another without intermediate settling stages and finally to a final settling stage. A "primary' dispersion is maintained in each mixing stage and controlled stepwise pH adjustment of the mixing stages is effected by metered addition of a base. such as ammonia.</p> |
