The leaching behaviors of Zinc and Manganeses of spent alkaline battery in sulfuric acid solution by using H2O2 as a reducing agent were investigated according to concentration of H2SO4, temperature, solid/liquid ratio and rotating speed of stirring bar. And base experiment for Mn-Zn Ferrite using the leaching solution was done. The experimental results of Zinc and Manganeses dissolution rates obtained at 100g/L solid/liquid ratio, 3.0M H2SO4, 60°C and 200rpm were 97.9% and 93.9%. After coprecipitation of leaching solution at pH 12, 80°C, O2 1.3L/min and 500rpm, Mn-Zn Ferrite was synthesized directly at low temperature.
