The IPE-A, self-developed organic acid leaching agent, was used to leach the valuable metals and separate Al foil from the LiNi1/3Co1/3Mn1/3O2 cathode scrap of production waste. The results showed that the best recovery conditions were as follows: organic acid IPE-A concentration of 3.5 mol/L, the H2O2 concentration of 4%(?), solid to liquid ratio of 40 g/L, reaction temperature of 60℃ and reaction time of 40 min. The leaching rates of Ni, Co, Mn and Li reached 93.45%, 94.54%, 96.41% and 98.17% respectively, while the leaching rate of Al was only 2.07%, which can be neglected, and the positive cathode material and aluminum foil can be separated well. Avrami equation could be used to correlate the experimental data of the leaching reaction, and the activation energies of Ni, Co, Mn, Li were 36.30, 36.71, 36.47, 33.21 kJ/mol. The reaction velocity was controlled by chemical reaction step.
