The Real Deal: Sri Lanka – The Best Graphite in the World
This graphite has a current estimated market value in its raw form of $2,000 – $2,500 a ton. If upgraded to a battery standard of 99.99% Cg, could be sold for upward of twice that amount. This is a substantial margin, while other companies in the graphite mining world are looking at immense capital expenses to come into production.
