Abstract
The present invention relates to a process for the recovery of transition metals from battery materials comprising (0.1) providing a battery material which comprises oxidic nickel and/or cobalt compounds, (1.1) heating the battery material above 350° C. to yield a reduced material which contains 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 yield a solid carbonylation residue and a volatile carbonyl which comprises nickel and/or cobalt carbonyl containing compounds, and (3.1) separating the volatile carbonyl from the solid carbonylation residue by evaporation.
