Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr per ton of primary aluminum. [18] Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is ...
The company originally expected to idle the plant ― once its largest U.S. smelter and “the largest producer of high purity primary aluminum in North America” ― for less than a year, but it ...
The new smelter would double the size of the current U.S. primary aluminum industry while avoiding an estimated 75% of emissions from a traditional smelter due to its state-of-the-art, energy ...
Here’s a timeline of what happened with the Alcoa Intalco Works facility west of Ferndale.
A typical smelter contains anywhere from 300 to 720 pots, each of which produces about a ton of aluminium a day, though the largest proposed smelters are up to five times that capacity. Smelting is run as a batch process, with the aluminium deposited at the bottom of the pots and periodically siphoned off.
Rio Tinto Alcan operates Iceland's first aluminium smelter (plant name: ISAL), in Straumsvík, near the town of Hafnarfjörður. The plant has been in operation since 1969. Its initial capacity was 33,000 metric tons (t) per year, but it has since been expanded several times and now has a capacity of about 189,000 t/yr.
