Zusammenfassung:The invention discloses a method for wet processing of high antimony-lead anode mud, which comprises the following steps: putting high antimony-lead anode mud of which the content of antimony generated during the lead electrolysis is between 40% and 75% in hydrochloric aid medium, adopting two-section electric potential control of chlorination leaching, wherein oxidation-reduction potential of the end point of the first section chlorination leaching is controlled to be between 200-300mv, while oxidation-reduction potential of the end point of the second chlorination leaching is controlled to be 400-450mv, and 99.5% of golden and 99% of silver are enriched in the slag of the second chlorination leaching and can be subjected to further process. The silicofluoric acid in the first section chloridizing leachate is evaporated by concentration and distillation, the high-purity antimony butter is prepared from distilled and concentrated mother liquor by a continuous distillation method, and the yield of antimony met
