particle size as the target grind size for the ball mill circuit; for ex-ample, it is convenient to select the desired 80% passing size as the target grind size. You can then use this target grind size to define and distinguish between "coarse" and "fine" particles in any of the given circuit streams. Coarse particles are therefore larger than the circuit target grind size. Fine particles are
