In graphite flotation, a variety of nonpolar oils such as kerosene and fuel oil are generally used in combination with frothers such as pine oil or higher alcohol. In many respects, graphite responds to flotation in a similar way to coal or molybdenite. The pH of the pulp is usually adjusted to about pH 8.

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 …
