| titleOfInvention | Indium recovery method |
| abstract | The present invention relates to a method for recovering indium, wherein a dissolution step of dissolving an indium content in hydrochloric acid to prepare an indium solution, neutralizing the solution of the indium solution to 2.5 to 3.5 by adding an alkali to the indium solution. Neutralization step, aging step of aging the neutralized indium solution, adding a sulfiding agent to the aged indium solution so that the pH of the aged indium solution is 2 to 3, and then the resulting sulfide is removed And a sulfidation step, and an indium dissolving solution having undergone the sulfidation step as an electrolytic solution, and an electrolysis step of electrolyzing indium under an electrolytic condition of 3.5 to 4.5 V.n n n By using the indium recovery method, high purity indium of 99.9999% or higher purity can be recovered, and the process cost can be reduced by not using indium as an anode during electrolytic extraction, and further purification processes such as ion exchange treatment (cementation) This eliminates the need for a shorter process.n n n n Indium, Recovery, ITO, LCD, Solar Cell, Purity, High Purity, 6N, Hydrochloric Acid, Soluble, Alkali, Neutralization, Sulphide, Sulphide, Insoluble Anode, Electrolytic |
