The size of the graphite flake is a very important commercial consideration. Although one can manufacture small flake from large flake, the converse is not true. Therefore, it is in the best interest of a flake graphite producer to maximize the amount of large flake removed from the deposit. This means that any processing which will tend to grind or reduce the size of constituent flake must be minimized. The crushing and grinding of ore to release entrapped flake is the main force responsible for reducing the size of the individual flakes extracted.
