Abstract：Cobalt was recovered from the low acidic leaching residue of spent lion batteries by sulfating roasting-leaching process. X-ray diffraction shows that Co3O4 is the main phase of raw materials that is difficult to leach. The results show that nearly 99.86% of cobalt is leached out under optimal conditions, the roasting temperature is 350 ℃, H2SO4-to-raw material mass ratio is 0.8, and roasting time is 1 h.
