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 aluminumenriched soils are the result of the decomposition and lateritic weathering of nepheline syenite an intrusive igneous rock during the
Oct 06 2017 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
The bauxite residue sinks to the bottom of the settling tanks then is transferred to the washing tanks where it undergoes a series of washing stages to recover the caustic soda which is reused in the digestion process further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters
Bauxite rock largely composed of a mixture of hydrous aluminum oxides bauxite is the principal ore of aluminum bauxites vary physically according to the origin and geologic history of their deposits some deposits are soft easily crushed and structureless some are hard dense and pisolitic
The study reveals the key drivers of the bauxite industry bauxite is the most important aluminum ore application of aluminum in vehicle manufacturing is increasing rapidly due to the associated benefits such as corrosionfree highdensity and lightweight features that make aluminum desirable for
