Bauxite Mining and Alumina Refining: Process Description

The major steps in alumina refining are as follows 1–3: 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 Separation andBauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location Before mining can commence the land needs to be cleared of timber andMining and Refining – Process World Aluminium
