Rhenium recovery method |
| abstract |
PROBLEM TO BE SOLVED: To reduce the environmental burden and reduce the cost and eliminate the influence of impurities on the recovery of rhenium when separating and recovering rhenium from an aqueous solution of rhenium containing impurities using an anion exchange resin. Thus, a method for efficiently separating and recovering rhenium is provided. An aqueous solution containing impurities together with rhenium is passed through a quaternary ammonium salt type anion exchange resin to adsorb rhenium, and then 1.5 mol / l to the anion exchange resin adsorbed rhenium. The rhenium is eluted by passing through a sulfuric acid solution having a concentration of 3.5 mol / l or less, and the rhenium in the obtained solution after elution is separated and recovered as a sulfide by adding a sulfurizing agent.
