The smelter has been curtailed since May 2014 and the underlying market conditions that led to the curtailment have not improved.
“The closure of the Poços smelter permanently removes a high-cost smelting facility from the Alcoa system and is another step in creating a more profitable Primary Metals business,” said Alcoa Global Primary Products President Bob Wilt.
