Aluminum processing, preparation of the ore for use in various products. By the 18th century, the earthy base alumina was recognized as the potential source of substantial amounts of aluminum in the Ural industrial complex, and by 1990
by a combination process; the alumina is subsequently smelted to aluminium via a (especially iron), producing a complex solution from which the aluminium
The Bayer process is the principal industrial means of refining bauxite to produce alumina in the digestion of bauxite with sodium hydroxide. It has high calcium and sodium hydroxide content which makes a complex chemical composition.
Roughly 85% of mined bauxite is processed via the Bayer Process to make alumina .. in 100's M$. • Wet chemistry is too expensive and too complex to apply to.
