Graphite flotation - GIESSEREILEXIKON.COM

Graphite flotation. Graphite diffusing from cast iron melts rising to the top of the melt. In metallographic specimen floating graphite is very clearly identifiable even with low degree of magnification. At broken or machined surfaces, the diffused and floated spherolites can be identified as dark spots even with the unaided eye ( Figures 1 to 3 ).

I would think that you are not too worried about maximising the size of the graphite particles so gentle attrition is the way forward. You need to have a way to physically separate the clay from the graphite before attempting the separation, which would probably consist of classification (depending how fine the graphite has become) then flotation in the presence of dispersant at low percent ...
