May 08, 2014· PROCESS DESCRIPTION: BAUXITE MINING. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica.

Guinea is very interesting: the quality of its bauxite deposits is much better given the concentration of minerals, the reserves are important, and it has low content of silica oxide which complicates the aluminum transformation – William Morrell, vice president of Global Emirates Aluminium (EGA), project Guinea Alumina Corporation (GAC)

The use of the gravity concentration process, including classification in cyclones, and magnetic separation proved to be feasible for the bauxite from CBA's operations. Plant production and available alumina increased as a result of their application.

Digestion. Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such,...
