Recovery of germanium from aqueous solutions

Germanium is recovered from aqueous solutions containing germanium, zinc, and antimony by sorption with an ion exchange resin which has as its matrix a backbone polymer to which are attached amine active groups chosen from secondary and tertiary amines and quaternary ammonium groups. The resin exhib...

Beschreibung
Zusammenfassung:	Germanium is recovered from aqueous solutions containing germanium, zinc, and antimony by sorption with an ion exchange resin which has as its matrix a backbone polymer to which are attached amine active groups chosen from secondary and tertiary amines and quaternary ammonium groups. The resin exhibits a high selectivity ratio of germanium relative to antimony. The method is particularly useful for the recovery of germanium from materials or electrolytes encountered in the recovery of zinc from ores and complex concentrates.
