Vein graphite is formed by fluid deposition, i.e. the transformation of oil precursors. The second discernible type of macro-crystalline graphite is so-called “flake graphite”. This material is found disseminated in metamorphosed silica-rich quartzites, gneisses and marbles. The graphite content in the raw ore can vary from 5 to 40%.

Natural flake graphite is formed when carbon material is subjected to high pressure and high temperature. The carbon source material can be either organic or inorganic, although most commercially sourced flake graphite comes from organic deposits. The pressure required is usually greater than 1 gigapascal (75,000 psi) and the temperature needed is usually higher

Natural graphite is a crystalline mineral of pure carbon which normally occurs in the form of platelet-shaped crystals. It has important properties, such as chemical inertness, low thermal expansion, and lubricity, that make it almost irreplaceable for certain uses such as refractories and steelmaking. Graphite ore types are crystalline (flake and lump} or 'amorphous'
