The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

The effect of highenergy milling on the surface properties of quartz is examined with regard to its pregrobbing behavior towards gold. A standard ring mill is used to process dry quartz samples, and the changes in the morphology of the particles, structural deformations and surface chemistry are investigated to explain the increased pregrobbing ability of quartz in acidic chloride solutions.

Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
