Graphene requires highest purity graphite, page-4

Well the most important point is that veiners do not need to dig big massive holes into the ground to get the graphite out.

We do not need to refine the graphite as much to get it to high purity C content.

All of this requires very high capex for mining and refining operations.

All of the vein high purity graphite will go to creating value added graphene applications.

Small tonnage yet commanding very very high prices.
