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 quality is impacted by the content of alumina and alumina containing minerals like gibbsite boehmite and diaspor and the amount of reactive silica goethite haematite and other impurities The wide range in the composition of the different bauxite ores derives from the differences in the origin and geologic history of
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
