Hydrometallurgical Processing
Nan et al. studied a new process for recovering metals from a mixture of worn lithium-ion and nickel-metal hydride (NiMH) batteries. In the developed process, liquid-liquid extraction was used to remove copper, cobalt and nickel from the obtained leachate. Using the developed process, it was possible to recover more than 94 % of all metals.
