Alcoa Intalco Works produces primary aluminum metal by the Hall-Heroult reduction process. The plant has three operational potlines, with two of the three potlines idled. The smelter is capable of producing 278,000 mtpy. Its current capacity is approximately 90,000 mtpy.
The Smelting Process
Aluminum is processed from a raw material called alumina, which is produced from bauxite ore in Australia. One ton of aluminum is smelted from two tons of alumina. That one ton of aluminum is enough to make 60,000 beverage cans or the spaceframes for seven full-size cars. Intalco is a smelter that dissolves the alumina in a cryolite bath inside large, carbon-lined cells called pots. When a powerful electric current is passed through the bath, aluminum metal separates from the chemical solution and is siphoned off. That molten aluminum goes into furnaces for precise mixing with other metals to form various alloys with specific properties designed for particular uses. It is then poured into molds or cast into ingots. This is the finished product, which leaves Intalco primarily by truck. Further fabrication may include casting, rolling, forging, drawing or extruding to make thousands of different finished products from beverage cans to jet aircraft – either by Alcoa or by its customers.
The union at Alcoa Intalco Works is the International Association of Machinist and Aerospace Workers .
