| titleOfInvention | Comprehensive recovery processing method for indium-containing aluminum-substituted sponge indium solution |
| abstract | A comprehensive recovery processing method of indium-containing aluminum-substituted sponge indium solution, belonging to the field of hydrometallurgy. The invention adopts calcium oxide or calcium hydroxide to neutralize the solution after the chlorine-containing aluminum replaces the indium until the pH value is 4.5-5, the indium hydroxide is hydrolyzed and precipitated, and then sodium hydroxide is used to continuously neutralize the indium hydroxide filtrate to react with the aluminum chloride in the indium hydroxide filtrate to generate Na 3 AlO 3 Reacting with calcium chloride to obtain calcium hydroxide precipitate, filtering to obtain filtrate, neutralizing with hydrochloric acid to obtain Na 3 AlO 3 The technical process flow of hydrolyzing to generate aluminum hydroxide precipitate, filtering, concentrating the sodium chloride filtrate, electrolyzing and respectively recovering chlorine and sodium hydroxide overcomes the defects of incomplete comprehensive recovery and environmental protection treatment of the traditional technical process. |
