A novel method for producing an indium- containing metal which comprises mixing an indium-containing solution with oxalic acid as a precipitating agent, to form a precipitate of indium oxalate, recovering the precipitate through solid-liquid separation, dissolving the precipitate in an acid to form a solution, inserting an aluminum plate into the solution, to form sponge indium by substitution with aluminum, and then subjecting the sponge indium to alkaline casting, to prepare an indium-containing metal. The above method can be suitably employed for producing an indium-containing metal by the use of, as a starting material, an indium-containing solution prepared by dissolving an indium-containing material obtained by the recovery of the indium being scattered during the manufacture of an ITO thin film with an acid or the like, with high efficiency in good yield. |
