    This invention relates to wet metallurgy, especially a process for recovering Ge from solution by extraction and counter-extraction. This process features that ammonia gas or ammonia water is used for direct hydrolysis from counter-extracted solution to obtain crude GeO2 and the hydrolyzed mother solution containing ammonium fluoride may be used again. According to the invention, the separation of F from Ge is simple and efficient, counter-extraction rate is increased, and the consumption of reagent is reduced.
