PROCESS, APPARATUS, AND SYSTEM FOR RECOVERING MATERIALS FROM BATTERIES

A process for recovering materials from a black mass material obtained from lithium-ion batteries can include: i) conveying a black mass material as a black mass solid stream; ii) leaching the black mass solid stream to form a pregnant leach solution and residual solids; iii) separating the pregnant...

Zusammenfassung:	A process for recovering materials from a black mass material obtained from lithium-ion batteries can include: i) conveying a black mass material as a black mass solid stream; ii) leaching the black mass solid stream 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 from the pregnant leach solution; vii) isolating a cobalt (Co) product from the from the pregnant leach solution; viii) isolating a nickel (Ni) product from the from the pregnant leach solution; ix) isolating a salt by-product from the pregnant leach solution; and x) isolating a lithium product the pregnant leach solution.
