Due to the strong floatability of graphite, flotation is the most commonly used method of graphite beneficiation. Among them, crystalline flake graphite has the best floatability, followed by vein graphite; amorphous graphite has the poorest floatability [ 3, 6, 7, 8, 9, 10 ]. Therefore, flake graphite can be easily purified by flotation.
