<p>PROBLEM TO BE SOLVED: To provide a method for efficiently recovering indium from high purity oxidized indium-containing scrap generated at the time of producing an IXO sputtering target or after its use. SOLUTION: In this method for recovering indium, IXO indium-containing scrap is dissolved with hydrochloric acid to obtain an indium chloride solution, the pH of the solution is controlled, and after that, indium is substituted with zinc and is recovered.</p> |
