Graphite Flotation
MeltLabGuy (Materials) 6 Jan 10 15:20. Carbon flotation in ductile iron is caused when the foundry allows the Carbon Equilivant to exceed the ability of the magnesium to suppress graphite formation in the liquid. My experience suggests that limit is about 4.55 - 4.60 with moderate levels of magnesium 0.030 to 0.035%.

Recovery of carbon and cryolite from spent carbon anode slag of
A grinding flotation process was proposed to separate and recover the LiCoO 2 and graphite from spent lithium-ion batteries (Yu et al., 2018). The flotation performance of carbon anode slag through process optimization (a closed-circuit process of one roughing, one scavenging and two cleaning) was significantly improved (Mei et al., 2016).
