  • Bauxite Mining and Alumina Refining

    Bauxite mining and alumina refining are the upstream operations of primary aluminum production This review article describes the industrial processes of bauxite mining and alumina refining and outlines the physical, chemical, biological, ergonomic, and psychosocial health risksMethods/design: A group of workers occupationally exposed to aluminium in an open bauxite mine were compared with a group of nonexposed wood processors Serum aluminium was analyzed using atomic absorption spectrometry Data from the clinical chemistry of the blood and a questionnaire were used to explore determinants for aluminium exposureSerum aluminium levels of workers in the bauxite minesBauxite mine tailings can be used as the reserve resources of aluminium and lithium In this study, a less energy consumption treatment method for extracting aluminium and lithium from bauxite mine tailings has been proposed, which used mixed acid to leach aluminium and lithium from tailings directly, avoided roasting for reducing energy consumption, and obtainedExtraction of lithium and aluminium from bauxite mine
