Recovery of Gallium and Germanium from

The occurrence relationship between Fe and Ga and Ge in the reduced iron powder obtained from zinc residue, was analyzed by chemical phase method. The results showed that the gallium and germanium contacted with the metallic iron to form an alloy mainly in a form of solid solution,therefore,physical methods couldn't separate iron from gallium and germanium.

Study on Recovery of Gallium and Germanium from

Hydrometallurgical zinc residuce contains a large amount of gallium and germanium that are of extremely high comprehensive recovery value. A new technology for the reduction and separation from hydrometallurgical zinc residue is developed by making use of the Ga and Ge's affinity for iron. The technology intensifies the reduction process of zinc residue to realize an oriented enrichment of Ga

2017-5-1  1. Introduction. Gallium and germanium are important strategic resources that have been used extensively in a variety of high-technology fields, such as semiconductors, infrared optics, optical fibers, medicine and catalysis (Schimmel et al., 2001, Tyszczuk et al., 2007, Depuydt et al., 2006, Fujiwara et al., 2003).So far, no independent germanium and gallium ore deposits have been found in

Increasing germanium extraction from hydrometallurgical

1993-2-1  Previous studies at the US Bureau of Mines (UTY) have shown that only 70% to 80% of the germanium in domestic zinc process residues can be extracted during H2SO4 leaching. To increase germanium extraction, the UTY developed and researched the hypothesis that minor amounts of germanium and zinc silicate, present in zinc calcine, dissolve during the leaching stages of zinc processing, forming
