RESULTS AND DISCUSSION
Ideal Flotation Behavior
The flotation of pristine spheroidized natural graphite
and NMC111 was investigated to determine the effect
of Cyrene pre-treatment (i.e., heating at 100°C and
solvent pH ~1.8) on their surface properties. Graphite and
NMC111 possess hydrophobic and hydrophilic properties,
respectively (Vanderbruggen et al., 2021). After Cyrene
pretreatment and single-component flotation, the pHs of
the process water with graphite and NMC were 7.7 and
