This process is concerned with solvent extraction of Ge from zinc sulfate solution with 7815 (hy-droxamic acid as) extractant, sulfonated kerosene as diluent, T reagent as additive and NaOH as re-extract ant. The feed liquid is the leachate of Yunnan Huize lead-zinc ore leached at high temperature by strong sulphuric acid and ferric solution. The temperature is about 70~80℃ . The concentration of sulphuric acid and ferric inos are 90 g/L and 10〜15 g/L respectively. Selection of extraction system, metal exaction balance, process parameters, process design and the overall process experiment have been investigated. The Ge extraction is higher than 96% , are re-extraction is higher than 97% , Ge conlent in the germanium concentrate, which is ohtained by nentralization is higher than 30% .
