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 …

Bauxite is a mineral made up primarily of aluminium oxide mixed with some other minerals. Bauxite is regarded as high quality if it contains more than 50% of aluminium oxide. Bauxite supplies Confirmed global bauxite supplies are estimated at 18.6 billion tonnes. At the current level of extraction, this should last for more than a hundred years.

Bauxite ore is crushed in a high temperature, rotating grinding mill, where it is mixed with sodium hydroxide. This produces a slurry (thick liquid) of sodium aluminate and small amounts of other metals. 2. SLURRY TANK: The 'other metals' are heavier than the sodium aluminate and sink to the bottom of the slurry tank, where they are removed. 3.
