TENORM: Bauxite and Alumina Production Wastes. Bauxite refineries produce alumina (aluminum oxide), which is used to create aluminum metal. Bauxite is also used to manufacture other industrial products, such as abrasives, cement and chemicals. There are two operating bauxite refineries in the United States, both of which are located in Louisiana.

According to CRU reports, the alumina industry's average production cash cost could reach $275/mt in 2013 and $320/mt by 2022. Orbite expects its production costs to be $208/mt of alumina. Factoring in the possible sale of byproducts, the costs could be reduced to a negative cost for alumina.
