Bauxite AIMR 2013 Australian Mines Atlas. The bauxite mines in the Darling Range have the world's lowest grade bauxite mined on a commercial scale (around 2730% Al 2 O 3). Despite the low grade, the mines accounted for 23% of global alumina production as they also have low reactive silica, making the bauxite relatively easy to refine.
Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrousnonferrous metal mine, coal, traffic, light industry, etc.
balls which exist in mill, 𝐴𝑏: each ball abrasion (g), 𝐴t: total ball abrasion in the mill (g), 𝑣b: each ball volume (m3), 𝑓b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for 𝑓b = 2%, total ball abrasion will get, finally.

Bauxite Mining and Alumina Refining Process Description . Wet grinding of the bauxite ore in rod mills ball mills or semiautogenous grinding mills to produce fine slurry. Digestion of the slurry by caustic soda (NaOH) at strengths exceeding 170 g/L in vessels under pressure at temperatures ranging from 145 to 265°C depending on the type of bauxite
· Mill HEAD LINERS. Head liners are of the segmental type constructed of Manganese Steel, Chrome molybdenum, or NiHard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills. For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner ...
With increasing need for fine and ultrafine grinding, stirred media mills became an alternative for conventional ball mills. In this study, samples of bauxite whose chemical composition and Hardgrove Index values are known were ground to micronized size by a laboratory scale stirred media mill and its performance was compared with a laboratory scale ball (Bond) mill.
