OSLO, June 22 (Reuters) – Norsk Hydro will reduce alumina output at the Alunorte plant in Brazil after a power cut that occurred when three power transmission towers collapsed at the company’s Paragominas bauxite mine, the company said on Monday.
Initial police findings concluded that some components had been removed from the overturned tower on Saturday, but it was too early to say whether the structure had been sabotaged, a Hydro spokesman said.
Alumina, which is distilled from bauxite, is used for aluminum production.
Repairing the power supply will take two to three weeks, during which the Alunorte plant will operate at 50-70% of full capacity, Hydro said.
The company does not expect significant customer impact from power cuts, he added.
The Paragominas Mine, located in the northern Brazilian state, sends bauxite to the Alunorte aluminum refinery in Barcarena through a 244 km (152 mile) pipeline.
Alunorte in turn supplies alumina to the nearby Albras aluminum plant as well as other metal plants throughout the world. (Reporting by Terje Solsvik Editing by David Goodman and Gwladys Fouche)
