Hydro Bauxite & Alumina

Bauxite and alumina represent the first two links of the value chain in the aluminium industry. Our operations include one of the world's largest bauxite mines and the world's largest alumina refinery.

Our bauxite mines are located in the state of Pará, in the northernmost part of Brazil. A significant portion of Hydro’s bauxite is further processed in the company’s own plants, but some of it is also sold directly to other companies.

We produce alumina at Hydro Alunorte in Brazil. Some of this is used as a basis for Hydro’s own aluminium production, but much is also sold to other companies.
