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 .
Alro SA, established in 1963, is one of the biggest aluminium companies in Romania and in Europe. It started operation in 1965. Alro's primary aluminium facilities are located in Slatina and currently are a smelter and processing facilities. It also includes a cast house, hot and cold rolling mills and an extrusion shop.
In 2004, RUSAL acquired a 90% interest in the Boxitogorsk alumina refinery in Russia and increased its holding in the Nikolaev alumina refinery to 100%. In 2005, RUSAL bought a 50% stake in the Komi alumina project from SUAL and became its partner in the project, which involved the construction of an integrated bauxite and alumina complex in ...
