WO2009077940A1 A method of grinding a mineral

A method of grinding a mineralcontaining ore, which includes grinding the mineralcontaining ore in a primary milling process and thereafter fine grinding the mineralcontaining ore in a secondary ballmill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ballmill. The pebbles have an average size which is relatively smaller than the

Using Ball Mills to Extract Raw Gold from Ores

The ore is sent into a singlecylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multicylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.
