Milling the mined ore through crushing and grinding. Ball or rod mills crush and grind the mined ore to fine particles, releasing molybdenite from the gangue (worthless rock). The grinding mills shown here reduce rocks from the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
