摘要： A process for selective liquid-liquid extraction of germanium from an aqueous acidic liquor containing, besides germanium, at least another metal selected from the group which comprises cadmium, zinc, cobalt and nickel. This process includes extracting germanium from said aqueous liquor by contacting said liquor with an organic medium containing a diluent and an extractant, said diluent being immiscible with said aqueous liquor. The major part of germanium passes from said aqueous liquor to an organic phase which is subsequently submitted to a stripping step by contacting with an alkaline medium, with formation of an aqueous phase containing the major part of germanium from said aqueous liquor.
