History

Gramercy Alumina Plant

Construction on the alumina refinery began in 1957 with the first shipment of alumina occurring two years later. Ocean going freighters supply the plant with bauxite (primary raw material) from the bauxite mine in Jamaica. Utilizing the Bayer process to chemically extract alumina from bauxite, the original plant was designed to produce 438,000 metric tonnes of alumina per year. The plant has undergone several expansions and modernizations since then to increase the output of alumina to 1.2 million metric tonnes per year. The Gramercy facility was originally owned by Kaiser Aluminum and Chemical Corporation. In 2004, we formed a joint partnership with Century Aluminum and purchased the Gramercy refinery and the St. Ann bauxite mining operations from Kaiser. In 2009, we became sole owner of the refinery, which now operates as Noranda Alumina, LLC.
