Products - Bauxite | Noranda Bauxite

At Noranda Bauxite, we mine and ship high-quality bauxite with low-cost processing characteristics. Our bauxite has a silica content of less than 2% and a small particle size. This means the process for crushing and grinding is not as intensive. The small particle size and low silica content make our Bauxite one of the highest in value worldwide.

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. During the ...
