| Abstract: | Germanium and its compounds are widely used in electronic industry,infrared optics,optical fiber communications,chemical catalysts and other fields.With the significant increase in the market demand for germanium and the severe situation of solid waste resource disposal,the technology for recovering germanium from secondary resources has attracted more and more attention.The methods of recovering germanium from secondary resources such as zinc leaching residue from hydrometallurgy and waste optical fibers,and their advantages and disadvantages are summarized.The solvent extraction method and ion exchange method have the advantages of good selectivity and high recovery rate andare the future development direction of germanium recovery. |
