PROCESS FOR REMOVING IMPURITIES FROM SOLVENT EXTRACTION SOLUTIONS. |
abstract |
A process for regenerating an amine-type extractant used for metal recovery involves contacting an organic liquid phase containing an amine complexed with one or more metals with an aqueous solution essentially devoid of chloride ions to extract a or more metals of the organic phase. The extracted organic phase is then contacted with a hydrochloric acid solution to regenerate the amine extractant which can then be recycled to a production process. |
