If you haven't machined it, it's a piece of cake. Do you know what
grade it is? Brand?

Most are very abrasive but you can go as fast as your spindle will
allow. It machines more easily than magnesium. I machined a lot of
thread-cutting electrodes from Poco 3 graphite a few decades ago
Easy-peasy. Don't be afraid of it.

Wicked messy though. Graphite dust everywhere. I bought some equipment
from a shop that did a lot of graphite machining and it was a dusty mess.

How much can you get capturing and reselling the stuff?

About zero. Solid blocks of graphite are expensive (energy-intensive)
to make. Graphite dust is roughly the same material as carbon fly ash,
which they scrape out of the smokestacks of coal-burning electrical
generating plants. g
