This mill uses only one large ball diameter of 50 mm and the media of the ball and vial can be stainless steel or ceramic tungsten carbide WC. The milling chamber, as illustrated in Fig. 1b, is sealed with an O ring so that the atmosphere can be changed via a valve. The pressure is monitored with an attached gauge during milling.

pentlandite in the ore occurs as exsolutions in the pyrrhotite and the grain sizes ranges from 8 to 38µm. about 25 of the nickel bearing pentlandite is medium grained and subhedral. This kind of pentlandite occurs along the cracks of pyrrhotite or as inclusions in pyrrhotite. The rest of pentlandite present is disseminated in the gangue matrix.
