Abstract
The U.S. Bureau of Mines investigated solvent extraction methods for recovering germanium from sulfuric acid leach filtrates. A new organic extractant system was developed that synergistically and selectively recovered germanium from these solutions. A continuous solvent extraction circuit was operated for over 150 h, extracting over 90 pct of the germanium from 0.30-G/l ge filtrates containing 40 to 60 g/l free acid. Over 90 pct of the loaded germanium was stripped from the organic phase with water at 75 deg c. A section on germanium and gallium co-extraction is also presented.
