- Note: The only alumina refinery in Romania and the main supplier of the Alro smelter in Slatina. Bauxite arrives via the Danube and by sea, mainly from Guinea and Sierra Leone. The plant has gone through shutdown periods forced by the cost of natural gas; its operation is a condition of Alro’s raw material self-sufficiency.
