Next, bauxite is extracted by digging, ripping, and blasting, all of which creates dust plumes. Following extraction, bauxite is trucked along haul roads to stockpiles where it is then loaded onto trains, or in some cases larger trucks, for transport to port facilities for further processing — washing, crushing, and drying — and shipping.

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

Bauxite, the raw material for the production of alumina, was first discovered in 1924 at Kijang, Bintan Island, in the province of Riau, in northwestern Indonesia. Bauxite from Bintan Island has been mined and exported since 1935. In 1968 ANTAM acquired the mine. Thus, ANTAM is Indonesia''s longest running producer of bauxite.
