From one of germanium and gallium-containing oxalic acid solution of gallium and germanium selective extraction method

The present invention discloses a solution containing oxalic acid from gallium and germanium, gallium and germanium extraction method is relatively organic gallium and germanium oxalate solution was subjected to single or multiple stage countercurrent extraction, the organic phase was extracted countercurrently load with an acid solution single- or multistage countercurrent gallium selectively back-extracted, the organic phase post stripping gallium germanium alkali stripping solution, respectively an aqueous solution containing gallium and germanium-containing aqueous solution; the method is effective to achieve the gallium and germanium and impurities copper, zinc and the like separation, which process is short, small chemical reagent consumption, low cost, easy to industrialize.
