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 rocks. These parent rocks have been exposed to long periods (millions of years) of weathering under tropical, subtropical, or very wet temperate conditions. Ninety percent of the known world bauxite resources are in tropical locations. Other deposits outside these latitudes have been exposed to long periods of intense weathering in their geologic past. The greatest concentrations of bauxite are in Central and South America, in West Africa, in particular Guinea, and then in India, Vietnam, and Australia. Some deposits...
