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.

The mineral bauxite is the starting point for production of aluminium metal. Aluminium is the third-most abundant element in the earth's crust. It is found in different types of minerals.
Bauxite is an ore that was first discovered in 1822; various other types of bauxite have since been found and they all contain about 50 % alumina. They are virtually the only type of ore used to extract aluminium.
Bauxite Hills: The Bauxite Hills deposit is located approximately 50 kilometres north of Pisolite Hills and 95 kilometres north of Weipa. In December 2012, Cape Alumina released a prefeasibility study that confirmed the technical and economic feasibility of a mine producing 5 Mtpa of bauxite over 10 years.
