Bauxite Grinding Similar

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 being processed.

How to Choose Bauxite Grinding Mill?

Bauxite is a soil-like mineral that mainly composed of alumina, which is white or off-white, and appears brownish yellow or light red due to its iron content. It can be ground into fine bauxite powder that has many applications. Bauxite is generally formed by chemical weathering or exogenous action.

The grinding behavior of the bauxite ore was evaluated by identifying the relationship between the remaining mass (%) fraction of each particle size vs. grinding time. Figure 5 a shows, as an example, the experimental data obtained for four selected sizes, namely 0.600, 0.300, 0.150 and 0.075 mm when the material filling volume ( f c ) was 5%.
