Efficient and economical recovery of lithium, cobalt

A combined process was presented to recover valuable metals from lithium nickel cobalt manganese (NCM) cathodes of spent lithium-ion batteries. In this process, the cathode scrap was first roasted with carbonaceous reductant, and then carbonation water leaching was employed to selectively extract Li from the roasted cathodes.
