Preserving Flake Size in an African Flake Graphite

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 ].

Graphite has multiple layers of parallel planar C 6 rings, resulting in a polymorphic crystal structure of hexagonal close packing (HCP) or rhombohedral, in which the in-plane C-C bond length is 0.14 nm. Comparatively, the size of benzene ring (or crystallographic vector a’s length in the HCP unit cell) is 0.25 nm, and the interplanar distance (or crystallographic c/2) is 0
