Mineral Processing. 5. Milling. Crushing typically takes Run-of-Mine (ROM) ore down to particle sizes ranging from 6mm to 25mm, depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm).
