Approximately 80 g of the pyrophyllite ore was fed to 250 cm 3 milling chamber made from tungsten carbide (WC) using 100 pieces of 10 mm in diameter WC balls. Therefore, balltoore ratio was 10 by weight and it was kept constant. The ore was drymilled for 30, 40, 50 and 60 min. Rotational speed of the mill was kept constant at 400 rev/min.
