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 ...
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 ...
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.
Aluminium is produced in over 200 smelters in approximately 40 countries. ... This list may not reflect recent changes. ... List of alumina refineries; S.
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.
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 .
Rusal Aughinish, Europe's largest bauxite refinery, is located on the island. [1] The site includes a deep-water jetty in the Shannon [2] through which the refinery imports bauxite from Guinea and Brazil and exports alumina to be refined into aluminium metal. [1]
