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

Graphite Mining Processing Equipment Flow Chart

Graphite Mining. 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.
