Bauxite Mining Encyclopedia of Arkansas

Bauxite Mining. 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.

Bauxite Mining The Australian Aluminium Council

Bauxite Mining. Aluminium is the most abundant metal in the Earth’s crust, occurring as bauxite which contains aluminium oxide. The first step in producing aluminium is mining this ore.
