The product 'cryolite' is an inorganic substance with a CAS no. : 01. It is called 'trisodium;hexafluoroaluminum(3-)' under IUPAC naming and its molecular formula is: AlF6Na3. It is solid under normal conditions of temperature and pressure and appears as a colorless to white crystall which is insoluble in water.

Secondary cryolite production from a potlining production facility in Russia was designed and put into operation in 1972 at Achinsk alumina refinery. The technology and the project were developed by the Irkutsk branch of VAMI to extract fluorides as cryolite. ... Quebec, where the material was treated and recycled. The SPL generated originated ...

The cryolite is natural cryolite and artificial cryolite, which are fluxing agents for aluminum smelting, and the artificial cryolite is mainly used in the aluminum smelting industry worldwide. The traditional production process of the artificial cryolite is a soda ash and fluoaluminic acid method, and the reaction formula is as follows:

This article gives a brief overview of the history of modern aluminium production, which started with the invention of electrowinning of dissolved aluminium oxide in molten cryolite (Na3AlF6)-based electrolytes in 1886. All primary aluminium production is still based on the same principles, although numerous improvements and adoptions have been developed over the …
