Sustainable Bauxite Mining Guidelines ii Executive summary . Bauxite, the primary ore used to make aluminium, is refined into alumina, which is then smelted into aluminium. Other uses of alumina include chemical grade applications. Bauxite demand has historically been met by a few large players in the market, which have operated large scale mines.
Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).

May 08, 2014· Hand-arm vibration syndrome seems to be rare in bauxite mining and alumina refining. Vibrating hand tools are not an important part of the process at bauxite mines, but are common at alumina refineries. Nevertheless, most bauxite mines and alumina refineries are located in tropical climates, so cold-provoked vasospasm is less likely.
Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.
