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

Bauxite in Jamaica Geo for CXC

Bauxite mining in LindenEconomic and environmental impact

Mar 12, 2017Later, the bauxite industry was further consolidated, with the opening of the Alumina Plant in 1961, where alumina was produced using the bauxite tailings or waste. At the plant some of the bauxite was transformed into alumina, before its export to world markets, for further processing into aluminum.

TENORM: Bauxite and Alumina Production Wastes Radiation

The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

Bauxite Wikipedia

OverviewFormationProduction and reservesProcessingSource of galliumSee alsoFurther readingExternal links

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

Mining and Refining Jamaica

Alcan (now Rio Tinto) has had a long history in Jamaica, constructing two alumina refineries there in the 1950s. In 2001 Alcan sold its bauxite mining and alumina plants in Jamaica but kept responsibility for many of the bauxite residue sites with the intention of safely remediating them to an agreed standard and transferring ownership to the Government of Jamaica.

Bauxite The Aluminum Association

During the strip-mining process, bauxite is broken up and taken out of the mine to an alumina refinery. Once mining is complete, the topsoil is replaced and the area undergoes a restoration process. When the ore is mined in forested areas, an average of 80 percent of the land is returned to its native ecosystem.

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock.
