Electrolytic anode slag from an electrolytic mill in Xiangxi was used as raw material，tartaric acid was used as reducing agent，sulfuric acid was used as leaching aid to leach anode slag and enrich lead simultaneously.Through the single factor experiment，the leaching engineering was optimized based on Box-Behnken Design（BBD） response surface methodology.Four factors were set，including leaching temperature，liquid-solid ratio，sulfuric acid concentration，amount of tartaric acid，and manganese leaching rate was taken as the response value.The optimal leaching conditions and the influence of independent factors on manganese leaching rate were investigated and optimized.The experimental results indicated that the optimal leaching conditions were：leaching temperature of 80 ℃，sulfuric acid concentration of 3.7 mol/L，liquid-solid ratio （mL/g） of 3.5，tartaric acid dosage of 1.5 g（1.1 times of theoretical dosage），leaching time of 1 h.Under these conditions，the leaching efficiency of manganese and lead was 98.27% and 0.16% respectively.At the same time，the effects on the leaching rate of anode slag from big to small were：sulfuric acid concentration，liquid-solid ratio，leaching temperature，amount of tartaric acid，leaching time.The leachate and leaching residue were characterized and analyzed，and the reaction mechanism was discussed.It had the characteristics of non secondary pollution，short reaction time，high leaching rate，and great separation effect between manganese and lead by using tartaric acid as reducing agent to leach manganese and enrich lead.This study could provide a theoretical basis for the resource utilization of electrolytic manganese anode slag.
