| Abstract: | The extraction separation of germanium from indium raffinate in zinc production was described. Using hydroxamic acid HGS98 as extraction reagent, P204 as synergism, kerosene as diluent and NH 4F as stripping, the extraction mechanism and conditions were investigated in detail. The results show that this process has the advantages of good selectivity, high recovery, and easy to be operated. It provides a new way to recover high valence metal germanium from metallurgical waste materials. |
