Primary grinding takes place in a ball mill. The ground product from the primary grinding process is first put through a jigger to recover the coarse gold particles then classified in a screw classifier. Classifier underflow goes back to the ball mill. The overflow, sized at about 85% less than 0.074 mm, is then sent to flotation.

The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8%, for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively ...

The essential ball mill components can separate the grinding media and keep the sizes of grinding media gradually reducing from coarse grinding chamber to fine grinding chamber. This makes sure that large grinding balls grind large materials and small grinding balls grind small materials. 2. Screening Ground Materials

Over 10 years the magnetic metal liner has been used in more than 300 full-scale ball mills at over 100 mine sites in China. For example, one set of the magnetic metal liner was installed in a 3.2m (D) x 4.5 m (L) secondary ball mill (60mm ball charge) at Waitoushan concentrator of Benxi Iron and Steel Corp. in 1992.
