Paragominas normally operates with two ball mills, and with one ball mill out for maintenance, production at Paragominas has been running at 50% of capacity since the beginning of March.
 
In preparation for this maintenance, Hydro’s Alunorte alumina refinery was operating with an inventory level sufficient to cover the planned maintenance period. With additional supply from the MRN bauxite mine, production at Alunorte has remained unaffected during the maintenance period.
 
Paragominas has a nameplate capacity of 9.9 million tonnes. Alunorte has a nameplate capacity of 6.3 million tonnes, and is the world’s largest alumina refinery. Both operations are in the state of Pará in Brazil.
