Vein Graphite

​

There are three main types of graphite: flake, vein, and amorphous. Of the three, Vein Graphite is the rarest. It is extremely pure with very high carbon content of up to 99.5%. It is a naturally occurring form of graphite found in veins within rock fissures in the form of needle-like crystals. Originating from hydrothermal fluids or decomposed organic matter, it boasts superior crystalline perfection, electrical/thermal conductivity and malleability, making it ideal for applications in advanced batteries, lubricants, refractories, and specialized electronics.

Vein Graphite is highly valuable because of its high grade and very limited availability. It is currently comercially mined exclusively in Sri Lanka. It is supplied directly from the mine, and therefore does not require primary beneficiation nor a tailings dam. It is also mined by underground methods giving it a small surface footprint. Sri Lanka is renowned for its high-quality vein graphite and is the only known producer in commercial quantities. Sri Lankan vein graphite is naturally the highest grade in the world.
