"“A graphite mine that
would produce at a 94-96% purity level. It
would have as much medium (plus-80 mesh)
and large flake (plus-50 mesh) as possible.
The lower the percentage of fine flake (minus-80 mesh), the better, since it is the most
abundant material in the market and thus has
the lowest selling price….”"

"It must be borne in mind that in-situ flake
size estimations don’t necessarily translate
directly to flake sizes produced by metallurgical processes such as gravity separation or
froth flotation"

the table on p2 shows pricing as higher for larger flakes.
