Jamalco’s 2012 Sustainability Report


Third Quarter 2014 Business Update

Alcoa’s roots in Jamaica go back to 1959 with the formation of Alcoa Minerals of Jamaica, a wholly owned subsidiary of Alcoa. The company mined bauxite for export, with the first shipment in 1963.

In 1972, the company began processing bauxite into alumina at a new refinery in Halse Hall, Clarendon, with a production capacity of 500,000 metric tonne per year (mtpy), and exporting alumina from its port facility at Rocky Point. The refinery's capacity was upgraded to one million mtpy in 1999, and then to 1.25 million mtpy in 2003. The completion of a further upgrade in March 2007 lifted the production capacity of the refinery to 1.425 million tonnes per year.

In 1988, the Government of Jamaica acquired a 50 percent share in the operations. The resulting company was name Jamalco, with Alcoa as the managing partner. Following the expansion completed in 2007, Jamalco is now owned 55 percent by Alcoa and 45 percent by the Government of Jamaica.

What We Do

Jamalco mines bauxite and refines it into alumina before exporting the alumina from its port at Rocky Point, Clarendon. On average, 2.5 tonnes of bauxite produce 1 tonne of alumina. The alumina is exported to aluminium smelters where it takes around 2 tonnes of alumina to produce 1 tonne of aluminium metal.
