GermaniumGermanium is a strategic material essential for electronics, optics, and solar cell applications. The U.S. relies on imports to satisfy over half of its germaniumGermanium demand; domestic extractionExtraction of germaniumGermanium would reduce market volatility and support independent growth. GermaniumGermanium does not commonly form ores in mineable quantities but can become enriched in metallurgical wasteMetallurgical waste streams. The present study involves a multi-staged hydro- and pyrometallurgical process for the recovery of germaniumGermanium from metallurgical wastesMetallurgical waste. ChlorinationChlorination and volatilization present a simple and effective pretreatment method of concentrating germaniumGermanium in an aqueous solutionSolution. Following pretreatment, germaniumGermanium is adsorbed onto magnetiteMagnetite particles, which are then magnetically separated from solutionSolution with high efficiency. AdsorptionAdsorption kineticsKinetics have been modeled, and competitive adsorptionAdsorption experiments with a common gangue element have been completed. ChlorinationChlorination experiments involving the volatilization of germaniumGermanium tetrachloride from a synthetic charge as well as a fumed slag sample have been completed. The influence of various surface functionalization’s on magnetiteMagnetite’s germaniumGermanium uptake has been investigated. Additional work quantifying the selectivity of magnetiteMagnetite particles for germaniumGermanium in multicomponent solutionsSolution is ongoing, with the goal of optimizing the final purification step.
