    The process is surfacebased rather than relying on absorption into the metal and then diffusion of carbon into graphene layers on the surface. The room temperature process eliminates the need for postproduction steps and reduces production from a tenhour/nine to tenstep procedure to a single step that takes five minutes.

    The graphite/orerock 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. In the cell the ore is mixed with water and "floatation agents".
