Abstract

Germanium as a strategic element is found in aqueous solutions of various mining industries. For selective separation of Germanium from an aqueous solution containing anionic complexant, tartaric acid, solvent Extraction and supported liquid Membrane (SLM) were used with Aliquat336. Affecting parameters such as extractant concentration, complexant type and concentration, and the concentration of the stripping phase containing hydrochloric acid, were investigated in the solvent Extraction system. According to the results, Germanium Extraction efficiency rose up to 100% by increasing the concentration of Aliquat336 by 0. 2 %v/v. In addition, tartaric acid was found to be the best anionic Germanium complexant. With the addition of 0. 275 mM tartaric acid, Germanium Extraction efficiency reached almost 99%. The highest stripping efficiency (99%) was achieved at the HCl concentration of 2 M. In the SLM system, 5 %v/v of Aliquat336 as a carrier was sufficient to transport 99% of Germanium in the feed to the strip phase. Comparing two systems, the transfer time of the Membrane system (510 min) is higher than that of the solvent Extraction system (15 min).
