FAQ
Frequently Asked Questions
Natural cryolite mining in Greenland ceased in 1987. The mineral is now produced synthetically for industrial use.
It dissolves aluminium oxide (alumina) and significantly lowers its melting point, making the electrolytic extraction of aluminium economically viable (Hall–Héroult process).
Yes, but it is extremely rare. Small deposits have been found in places like the Ilímaussaq complex in Greenland, Russia, Spain, and the USA, but the Greenland deposit was by far the most significant.
As a fluoride compound, it can release toxic hydrogen fluoride gas if heated strongly in the presence of acids or moisture. It requires careful handling in industrial settings.
A rare, white or colourless mineral, composed of sodium, aluminium, and fluorine, historically crucial for aluminium production.
Cryolite is usually formal, technical, scientific in register.
Cryolite: in British English it is pronounced /ˈkraɪə(ʊ)lʌɪt/, and in American English it is pronounced /ˈkraɪəˌlaɪt/. Tap the audio buttons above to hear it.
