Ceylon Graphene Technologies extracts its graphite from the rich soils of Sri Lanka which is home to the world’s purest graphite known as vein graphite. Sri Lanka is the only country to mine ultra-pure highly crystalline vein graphite with more than 98% of carbon purity in the world over the last 100+ years.

Vein graphite is named for its occurrence in veins and fissures along with the surrounding rock formations in which it was found. This variety of graphite is formed from the direct deposition of solid, graphitized carbon from subterranean fluids at high temperatures.
