MINERAL PROCESSING - MILLING MINERAL PROCESSING - MILLING Introduction Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size.
