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 5a 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%. It is observed that the experimental data are expressed well by Equation (1) and thus, grinding

Bauxite - an overview ScienceDirect Topics

The bauxite formed a bed averaging 2 m thick. The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite.
