Extraction Process of Aluminium from Bauxite Ore

Unlike other base metal ores, bauxite ore does not require complex extraction processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay.Bauxite grinding and handling aids | Solvay,Solvay’s CYQUEST® Bauxite Grinding Aids (BGAs) and Bauxite Handling Aids (BXDs) were developed to improve the handling and flow properties of moist bauxite. This technology offers significant financial and environmental benefits to the Alumina industry. CYQUEST® BGA positively impacts the rheological property of bauxite slurry by reducing the viscosity and stickiness during the grinding,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.
