Jul 20, 2002· The original flora and fauna of much of the land involved in bauxite mining is restored once mining operations have ceased. For all forest areas used for bauxite mining, 80% is returned to native forests, the rest is replaced by agriculture, commercial forest, or recreational area, thereby making the area more productive for the local community.
Bauxite is usually stripmined, 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.
