Process of recovering valuable metals from waste secondary batteries |
| abstract |
A process of recovering metals from waste lithium ion/Ni-H/Ni-Cd batteries, wherein the waste batteries are calcined and sieved to generate an ash containing metals and metal oxides. The invented process includes subjecting the ash to a first dissolution etching treatment, a first filtration treatment to obtain a filtrate containing Cd ions which are precipitated as cadmium sulfate, a second dissolution etching treatment for the filtered solid, and a second filtration treatment to obtain a second filtrate. Fe+3, AF+3 and rare earth metal ions in the second filtrate are precipitated as hydroxides by adding a base to the second filtrate. The remaining solution was extracted and counter-extracted to obtain aqueous solutions of Co and Ni ions, which were subjected separately to a electrolysis to deposit Co and Ni metals. Li ions in the Ni-exhausted residue solution was precipitated as carbonate by adding a soluble carbonate salt. |
