Aluminium life cycle - hydro

Bauxite mining About 7 percent of the earth's crust is aluminium, making it the third-most abundant element after oxygen and silicon. Aluminium production starts with the raw material bauxite. Alumina refining Aluminium oxide (alumina) is extracted from bauxite in a refinery. Alumina is then used to produce primary aluminium.

Extraction Process of Aluminium from Bauxite Ore

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.
