The acidic slag was used as raw material which produced in the process of electrolytic manganese processing,with hydrochloric acid as the leaching agent,a leaching process of calcium in electrolytic manganese residue was conducted.The results showed that under the conditions as follows：hydrochloric acid concentration of 3 mol/L,the volume-mass ratio of liquid to solid of 6 mL/g,the acid leaching temperature of 80 ℃ and reaction time of 60 min,the leaching rate of Ca reached 94.2%.The kinetic analysis of the acid leaching process indicated that the acid leaching process of calcium from electrolytic manganese residue was controlled by chemical reactions,following shrinking core mode with apparent activation energy of reaction of 43.96 kJ/mol and the reaction order of 0.872 5.
