Straumsvik aluminum smelter, operated by Rio Tinto Alcan in Iceland. Aluminium smelting is the process of extracting aluminium from its oxide, alumina , generally by the Hall-Héroult process . Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
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]
Construction began in 2004 and the facility contains a smelter, cast house, rod production and deep-water port. The smelter employs 450 people and produces 940 tons of aluminium a day, with capacity of 346,000 metric tons of aluminium per year. Fjarðaál means "Fjords Aluminium" in Icelandic. [5] [6]
In 2005, Alcoa began construction in Iceland on Alcoa Fjarðaál, a state-of-the-art aluminum smelter and the company's first greenfield smelter in more than 20 years, [52] albeit under heavy criticism by local and international NGOs related to a controversial dam project exclusively dedicated to supplying electricity to this smelter. The ...
An aluminum company has singled out northeastern Kentucky as its preferred site for a new aluminum smelter that would bring about 1,000 permanent jobs to an Appalachian region hard hit by the loss ...
Aluminium smelting is the most important power-intensive industry in Iceland. There are currently three plants in operation with a total capacity of over 850,000 metric tons per year (t/yr) in 2019, [34] putting Iceland at 11th place among aluminium-producing nations worldwide.
This is a list of countries by primary aluminium production in 2023. [1] Primary aluminium is produced from aluminium oxide which is obtained from bauxite and excludes recycled aluminium. Only countries with a minimum production of 100,000 tonnes are listed.
In 2005, Landsvirkjun produced 7,143 GWh of electricity total of which 6,676 GWh or 93% was produced via hydroelectric power plants. 5,193 GWh or 72% was used for power-intensive industries like aluminium smelting. [12] In 2009 Iceland built its biggest hydroelectric project to date, the Kárahnjúkar Hydropower Plant, a 690 MW hydroelectric ...
