This is a list of primary aluminium smelters in the world. Primary production is the process by which alumina is smelted to pure aluminum. [1] Secondary production is the process of recycling aluminum scrap into aluminum that can be used again. [2]
The company operates three aluminum smelters in the US, and one in Iceland. Construction of a fifth smelter in Iceland has been halted since 2009. All Century's operations produce primary aluminum, that is, aluminum from ore, rather than from aluminum scrap. In 2014, the company produced 881,000 metric tons of aluminum.

The Valco aluminium smelter in Ghana, powered by the Akosombo Hydroelectric Project; Fjarðaál in Iceland, powered by the Kárahnjúkar Hydropower Plant; Jharsuguda in Orissa, India, to be powered by its own 1,215 megawatts (1,629,000 hp) coal-fired power station.
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 ...
Alcoa had a smelting plant in Badin, North Carolina from 1917 to 2007 and continued a hydroelectric power operation there until February 1, 2017, when the Yadkin Hydroelectric Project was sold to Cube Hydro. [66] Alcoa also operates an aluminum smelting plant of similar size to the one in Tennessee in Warrick County, Indiana, just east of Newburgh.
Here’s a timeline of what happened with the Alcoa Intalco Works facility west of Ferndale.
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 ...
