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] Capacity here refers to metric tonnes of output aluminum. The list is incomplete and missing some ...
It is also commonly referred to as alumina or aloxite [1] in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite . Its most significant use is in the production of aluminium metal, although it is also used as an abrasive due to its hardness and as a refractory material due to its high melting ...
Aluminium is produced in over 200 smelters in approximately 40 countries. ... This list may not reflect recent changes. ... List of alumina refineries; S.
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.
Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery. This is an electrolytic process, so an aluminium smelter uses huge amounts of electric power; smelters tend to be located close to large power stations, often hydro-electric ones, in order to hold down costs and reduce the overall carbon footprint .
Alcoa World Alumina and Chemicals is a owned 100% by Alcoa Corp. and is abbreviated to AWAC. AWAC's business is the mining of bauxite, [1] the extraction of alumina (aluminium oxide) and the smelting of aluminium. It has about 25% of the global alumina market. Alcoa acts as the day-to-day manager.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
