procedure of using a ball mill for gold ore
Rod mills, how they function Mine
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...

The Mining Process – Waihi Gold
Ore from both open pit and underground is stockpiled separately at the mill before being fed into a mill with lime, water and steel balls. The larger particles from this mill are returned to the mill for more grinding. The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% < microns.
