• Vein Graphite is a special ore which is only mined in Sri Lanka. Only Sri Lanka Graphite is mined in tunnel pits, the other countries are open-pit mined.  Flake Graphite of other countries is contained in rocks and in stones at a rate of 10% or less, while Sri Lankan Vein Graphite has a purity of 90% or more even in low-grade ores since the vein themselves are graphitized.
• The main property is that it has a heavier specific gravity than Flake graphite, and it can produce large-particle graphite.  One of the other properties is that the total number of graphene production is larger and it is thicker than other countries’ products.

Main Applications

• It has been used as lubricants for a long time, and is often used for high lubrication parts, brake linings, and carbon brushes, etc.
