Investigation on Germanium Synergic extraction from synthetic solution

In this study, germanium synergic solvent extraction was investigated from synthetic acidic solution. Coal waste and zinc resources are the main resources for germanium extraction. Usually hydrometallurgical methods are used in procedure for germanium recovery. Di(2-ethylhexyl) phosphoric acid (D2EHPA) and LIX 63 were used to separate germanium form solution. The effects of pH, extraction time and stirring speed were investigated and results showed that the optimum pH was lower than 0.2. The optimum time was 3 minutes and in this time equilibrium was reached. By optimization of the parameters, more than 87% of germanium was extracted.
