Effects of ball milling on the surface area and pH of BR are illustrated in Fig. 3. The unmodified BR has a specific surface area (SSA) of 9.23 m2/g and a pH of 10.8.
Bauxite. Bauxite contains typically 40–60% aluminium oxide (alumina) in the form of several hydrous alumina phases (gibbsite, Al (OH)3, boehmite (AlOOH) and diaspore (ALOOH), and with smaller amounts of iron, silicon and titanium compounds as well as other trace impurities. From: Fundamentals of Aluminium Metallurgy, 2011.

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.
Research highlights Grindability characteristic of five different kinds of bauxite was investigated. Temperature and alkaline media have significant effect on the grindability. Possible reasons of the Bond work index decrease were revealed. The grinding work of bauxite should be divided by an empirical adjustment factor. The factor strongly depends on texture and type of bauxite being tested.
Finally the ball mill receives the bauxite along with spent liquor for wet grinding .The steel balls used for grinding is discharged in form of scats by a trammel screen on the grinding mill outlet to prevent blockage of pipe work and damage to pumps. The mill discharge pump,

The bauxite mine has an open circuit compartmented rod/ball mill, with an alkaline wet medium and at room temperature. The study consisted of sampling the grinding circuit, data collection from the plant historian system, a BWI test and particle size distribution, and Bond theory and power model calculations.
This study aimed to model bauxite grinding and assess the optimum material filling volume in a laboratory ball mill in order to improve mill and overall process efficiency. Modeling results can be used for the selection of the optimum mill size and operating parameters in order to obtain the desired grinding products and reduce energy consumption.
