The global graphite market
Natural and synthetic
graphite have different
applications and the markets and do not compete
Natural graphite, 3 different types
Amorphous graphite
Flake graphite
Vein graphite
50% of world output
Low grade metamorphic and contact
metamorphic formation from coal
49% of world output
High grade metamorphic formation from organic rich sediments
1% of world output 2CO = C + CO2
Why graphite
BGS: Graphite, one of the minerals most likely to be in short supply.
US Dept. of Homeland Security: USA will be hurt if terrorist disable Chinese graphite production.
1 million new EV’s = 5 new graphite mines
(30.000 t/a production)
(15 mines of the size of Skaland)
Graphene
Can be produced from flake graphite,
(presently in lab scale only)
