How Is Bauxite Formed? Reference

27/03/2020 Bauxite is usually strip-mined, because it is typically found near the surface of the local terrain. As of 2010, 70 to 80 percent of the dry bauxite is then used to create aluminum. This is done by a process of heating and cooling the bauxite with various other minerals and gases until alumina is created. Aluminum can be extracted from the alumina by electrolysis.
