Latest Patents

Victor N Saleh holds a patent for the "Recovery of germanium from aqueous solutions by solvent extraction." This patent describes an improved method for selectively recovering germanium from acidic solutions that typically contain other metals such as zinc, arsenic, cadmium, antimony, indium, copper, and iron (II). The method utilizes a multistage, countercurrent liquid-liquid extraction process. The extractant in the organic phase is an oxime, specifically 5,8-diethyl-7-hydroxy-6-dodecanone oxime, combined with at least one alkylphosphoric acid, such as di-2-ethylhexyl phosphate or a mixture with mono-2-ethylhexyl phosphate, dissolved in a hydrocarbon diluent. This mixed system demonstrates superior efficiency and selectivity for germanium compared to existing systems that use either oximes or alkylphosphoric acids alone.
