bauxite extraction grinding
Chapter 2. Production and Processing of Aluminum
Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.

grinding in the production of bauxite
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%.
