Bauxite Mining and Alumina Refining: Process Description

Process Description: Bauxite MiningProcess Description: Alumina RefiningPhysical RisksChemical RisksBiological RisksErgonomic RisksPsychosocial RisksBauxite 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. It contains mixtures of various minerals such as gibbsite, boehmite, hematite, goethite, Al-goethite, anatase, rutile, ilmenite, kaolin, and quartz. Bauxite is a residual rock formed from the weathering of various igneous, sedimentary, and metamorphic ro
