A PROCESS, APPARATUS, AND SYSTEM FOR RECOVERING MATERIALS FROM BATTERIES

The invention pertains to a process for recovering materials from a stream comprising black mass solids obtained from lithium-ion batteries, the process comprising:i) providing a stream comprising the black mass solids, lithium, cobalt, aluminum, manganese, nickel, iron, copper;ii) leaching the stream with an acid to form a pregnant leach solution and residual solids;iii) separating the pregnant leach solution from the residual solids;iv) isolating a copper product from the pregnant leach solution;v) isolating an aluminum (Al) and/or iron (Fe) product from the pregnant leach solution;vi) isolating a manganese (Mn) product from the pregnant leach solution;vii) isolating a cobalt (Co) product from the pregnant leach solution;viii) isolating a nickel (Ni) product from the pregnant leach solution;ix) isolating a salt by-product from the pregnant leach solution; andx) isolating a lithium product from the pregnant leach solution.
