    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).

    Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 of the gold under the condition that the ore size is 80 < 75 µm (Joe Zhou 2004). Complex ores meanwhile require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy 1994).
