Natural Flake Graphite | Asbury Carbons

At this point the individual flakes have been freed from the enclosing ore rock. The graphite/ore-rock slurry is then fed to froth floatation cells. Froth floatation is a method of beneficiation which relies on the differences between the surface chemistry of the country rock and the mineral being extracted, in this case graphite flake.

Preserving Flake Size in an African Flake Graphite Ore ...

As the high value and the scarcity of large-flake graphite ore resources, it is in the best interest to maximize the amount of large flakes and minimize any processing that will reduce flake sizes. In the study, the mineralogy of an African graphite ore was estimated using X-ray diffraction (XRD), X-ray fluorescence (XRF), and optical microscope analyses.
