| Abstract: |
| Gallium and indium are widely used in high-tech fields because of their excellent properties. With the development of science and technology, some advanced materials have an increasing demand for two metals, so the development of effective processes to separate and recover these two metals from primary or secondary resources is gradually being valued.. The paper mainly focuses on the recovery and separation technologies of gallium and indium at home and abroad in recent years. These methods involve solvent extraction, ion exchange, chlorination separation, electrodeposition, and so on. The technical principles and characteristics of different methods are analyzed, and the development direction of gallium and indium separation and recovery technology is prospected. |
