Bauxite Mining and Alumina Refining LWW

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 being processed.

Bauxite World Distribution and Bauxite Ore Market Analysis

Bauxite Ball Mill. Bauxite ball mill is composed of a rotary system, discharging system, feeding system, bearing system, transmission system, and lubrication cooling system. It mainly uses the mutual extrusion and grinding from grinding media to the raw bauxite ore. The grinding media is generally a samesized steel ball.

Bond Work Index an overview | ScienceDirect Topics

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 ...
