Commercial flake graphite products are available in a range of purities from around 80% carbon up to 99+ percent carbon. Flake which is in the purity range of 80-98% typically represent materials which have been beneficiated using only froth floatation. Flake above 98% purity has been purified using other methods subsequent to floatation.

On cooling, the iron cannot hold as much carbon in solution, and some of it comes out in the form of graphite flakes. Part of the graphite burns away, but much of it is wafted throughout the steel plant, where it falls as a continuous rain. More graphite is skimmed from the surface of the molten iron just before it is poured into the steel furnace.

Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.
