Ultra fine milling for the recovery of refractory gold

If the encapsulated gold is coarser in size, ranging say, from 1 or 2 microns to approximately 20 microns, then liberation can also be achieved by ultra fine milling (UFM). The Western Australian goldfields, like many others, contain numerous orebodies which are refractory in their primary zones. The mineralogy of these ores shows great
