The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining The bauxite is washed and screened before being converted to alumina a white powdery element from which the aluminum is produced Aluminum smelting is carried out in a Hall Heroult reduction cell which is lined with carbon A mix of alumina and cryolite is fed into the cell and carbon blocks Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum Usually between and inches thick foil is produced in many widths and strengths for literally hundreds of applications It is used to manufacture thermal insulation for the construction

May 08 32 BAUXITE MINING PROCESS AND ASSOCIATED OCCUPATIONAL HEALTH HAZARDS AND RISKS Although a very small percentage less than 1 globally of aluminum is derived from ores such as nepheline and from alternative sources such as fly ash from coal fired power stations bauxite mining represents by far the most common initial upstream step in the eventual production of aluminum Aluminium atoms easily bind with other metals forming compounds At the same time it s impossible to isolate aluminium by simply melting down the compounds in a furnace as is the case with iron for example The aluminium production process is much more complex and
