    Technical Report: The occurrence of graphite flotation

    2018-6-29Graphite flotation was observed to occur to an extent that depends on the carbon equivalent (C.E.) and casting modulus. In the present casting, graphite flotation occurred when the C.E. exceeded 4.42. Graphite particle clustering and graphite morphology degeneration into exploded nodules and compacted flake form was observed in the flotation zone.
