Recovering in, Ge and Ga from zinc residues

A novel solvent extraction process has been developed to selectively recover indium, germanium and gallium from the cement residue sulfuric acid leach solutions in a hydrometallurgical zinc plant. The key work was to determine a special organic molecule for gallium and germanium extraction. Continuo...

Zusammenfassung:A novel solvent extraction process has been developed to selectively recover indium, germanium and gallium from the cement residue sulfuric acid leach solutions in a hydrometallurgical zinc plant. The key work was to determine a special organic molecule for gallium and germanium extraction. Continuous countercurrent tests on the mini-pilot plant level were performed successfully with 90.7%, 94.2% and 92.9% yield from cement residue to metals, for indium, gallium and germanium, respectively.
