Thermal and gas purification of natural graphite for nuclear
The major impurities in natural graphite include Al, Si, Fe, K, and Ca. Thermal purification effectively reduces the impurity level of natural graphite. When natural graphite ores that have undergone beneficiation are used as feedstock, a purity of at least 99.9% can be achieved through thermal purification at 3000 °C for both FG and MG.

Graphite Processing
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 …
