Our upstream business is a vertically integrated producer of primary aluminum, consisting of a bauxite mine, an alumina refinery and an aluminum smelter.
Bauxite Mine—St. Ann, Jamaica—The bauxite mine provides all of the bauxite ore used for the production of alumina at our alumina refinery. In addition, approximately 40% of the bauxite ore produced by St. Ann is supplied to a third party refinery. The current annual production at St. Ann’s is 4.5 million tons of ore.
Alumina Refinery—Gramercy, LA—Gramercy processes bauxite, delivered from the bauxite mine in Jamaica, into smelter grade alumina for use in our New Madrid smelter. Gramercy also produces chemical grade alumina sold to third parties in the chemical industry. Current production capacity at the refinery is 1.2 million metric tons per year.
Primary Aluminum Smelter—New Madrid, MO—All of our primary aluminum production occurs at the New Madrid smelter, which produces approximately 263,000 metric tons of primary aluminum annually, at full capacity, accounting for approximately 15% of total 2009 United States primary aluminum production. The smelter, which is located near the midpoint of the Mississippi River, also includes a fabrication facility that converts molten aluminum into value added products such as rod, extrusion billet and foundry ingot.
