摘要： A method for regenerating an amine extractant used for recovery of metals involves contacting a liquid organic phase containing an amine complexed with one or more metals with an aqueous solution substantially free of chloride ions to strip the one or more metals from the organic phase. The stripped organic phase is then contacted with a solution of hydrochloric acid to regenerate the amine extractant which can then be recycled in a production process.
