crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus ½ inch, to a ball mill discharge sump. The combined mill discharges are pumped to undergo classifi cation, normally via hydrocyclones.

Furthermore, the influence of the type of mill was investigated, including reactions performed in different planetary and mixer ball mills, in a stirred media mill, and with a mortar mill. Comparisons with the other solventfree synthetic routes showed that ball milling is an effective way of performing the reaction with low energy intensity.
