METHOD FOR RECOVERING RHENIUM

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering rhenium not using an ion exchange resin or a solvent extraction method.SOLUTION: The method for recovering rhenium comprises: a step (S11) of adding bivalent iron ions (Fe)to a rhenium-containing liquid 1a; a step (S12) of adding a Ph regulator 3 to precipitate rhenium; a step (S13) of recovering precipitates 5 from a mother liquid 4 by solid-liquid separation; and a step of adding acid to the precipitates 5 to dissolve rhenium (S14) and producing a rhenium-concentrated liquid 6.
