Bauxite Facts

Bauxite is a mineral with a dull, earthy luster which is usually white or gray, though sometimes can be found stained by yellow, orange, red, pink, or brown by iron or included iron minerals. It has no cleavage, a low specific gravity, and the Mohs Hardness Scale score is between 1 and 3. Its streak is usually white, but its iron stain can discolor.

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.
