The present invention relates to a method for recovering transition metals from battery materials, the method comprising the steps of: (1.1) providing a battery material comprising nickel oxide and / or cobalt oxide compounds; (1.1) heating the battery material to greater than 350°C to produce a reduced material containing nickel and / or cobalt in elemental form; (2.1) carbonylating the reduced material with carbon monoxide, optionally in the presence of a reactive gas, to produce a solid carbonyl residue and volatile carbonyls comprising nickel carbonyl and / or cobalt carbonyl-containing compounds; and (3.1) separating the volatile carbonyls from the solid carbonyl residue by evaporation.

Methods and reactor systems are provided for extracting metals, such as nickel, cobalt, and iron, from reduced, activated metal compounds (“feed materials”). Feed materials may be derived from mixed hydroxide precipitate. Feed materials and carbon monoxide gas are delivered into an extraction reactor of a reactor system, such as a shell tube heat exchanger. A flow path therein directs the feed material downward and the carbon monoxide gas upward, enabling contact therebetween, forming at least one metal carbonyl gas and a solid residue therein. The flow path further directs the upward flow of metal carbonyl gases, and the downward flow of the residue. Methods and reactor systems may further purge the residue: using nitric oxide to convert any remaining dicobalt octacarbonyl therein to cobalt tricarbonyl nitrosyl gas; using an inert gas to removing any cobalt tricarbonyl nitrosyl therein; and using an inert gas-oxygen mixture, to form a passivated residue.

This invention relates to the recovery of nickel and cobalt from lithium ion battery materials comprising nickel, cobalt, and manganese, such as cathode active materials (CAM) and / or black mass (BM) derived from battery materials.
