As shown in Fig. 5, the flotation of pyrolyzed black mass without attrition pre-treatment resulted in a recovery of 91% graphite and 31% nickel-manganese-cobalt (Ni-Mn-Co) in the overflow product. The relatively high metal recovery in the overflow product suggests the ineffective separation between graphite and LMOs.
