Barcarena

In Barcarena, the bauxite from Paragominas and Trombetas is refined into alumina at our 91 percent-owned refinery, Alumina do Norte do Brasil S.A. (Hydro Alunorte).

Alunorte is the world's largest alumina refinery and has nearly 1,600 permanent employees and about 800 long-term contractors. Production at Alunorte started in 1995 and after three expansions now has a total capacity of over six million metric tons. A substantial portion of the alumina is shipped to aluminium smelters in other parts of the world, to support Hydro's own production and to other aluminium metal plants.

Some of the alumina goes straight to the neighboring business Albras, the second-largest aluminium metal plant in Brazil with 1,200 permanent employees and over 400 workers on long-term contracts. Hydro owns 51 percent of this business and the remaining 49 percent is owned by the Nippon Amazon Aluminium Company. Albras has produced aluminium since 1985 and has annual production capacity of about 460,000 mt. The company gets its electricity from the Tucurui hydro-power plant.
