| titleOfInvention | Recovery method of crude indium |
| abstract | The present invention provides a method for efficiently recovering crude indium having a purity suitable for electrolytic purification from an ITO target scrap in a high yield. The method includes the following steps (a) to (d). Step (a): The ground ITO target scrap is leached with hydrochloric acid, and then the insoluble residue is separated to obtain a leachate. Step (b): Zinc powder corresponding to 2-5 equivalents of the stoichiometric amount of the substitution reduction reaction with respect to tin in the leachate is added to the leachate, and it is noble from the indium that is reduced and deposited with sponge indium (1). A solid suspension of the impurity metal solids, and separating and recovering the sponge indium (1), an aqueous solution of indium chloride is obtained. Step (c): Aluminum is brought into contact with the indium chloride aqueous solution to obtain sponge indium (2). Step (d): Sodium hydroxide is mixed with the sponge indium (1) and the sponge indium (2), and then heated and melted to obtain crude indium. [Selection] Figure 1 |
