Bauxite Mining Encyclopedia of Arkansas

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.
