Extraction Process of Aluminium from Bauxite Ore

The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue.

Environmental Risks of Mining Massachusetts Institute

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Aluminum Smelting Furnaces and Processing of Bauxite

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
