The recovery of Ni, Co and Mn from spent battery material is very important to environment protection, utilization of resources and cost reduction of the material. The dissolution rates of Ni, Co and Mn with hydrochloric acid as leachant are all over 95% under the optimal conditions of initial hydrochloric acid of 6 mol/L, particle size of 120 pm for the exhausted scraps, molar ratio of H(2)O(2) to MeS of 2, leaching temperature about 60 degrees C, ratio of liquid to solid of 8, and leaching time of 2 h. The Ni(x)Co(y)Mn(z) precursor for cathode material prepared from the purified leaching solution, can meet the demand of precursor by pure chemicals. The process is economic and feasible for base metals from spent battery material.
