- Cryolite (Na3AlF6,
sodium hexafluoroaluminate) is an uncommon mineral identified with the
once large deposit at Ivigtût on the west coast of Greenland, which ran
out in 1987.
- It was historically
used as an ore of aluminium and later in the electrolytic processing of
the aluminium rich oxide ore bauxite .
- The difficulty of
separating aluminium from oxygen in the oxide ores was overcome by the
use of cryolite as a flux to dissolve the oxide mineral.
- Cryolite itself melts
below 900°C (1173 Kelvin) and can dissolve aluminium oxides sufficiently
well to allow easy extraction of the aluminium by electrolysis.
- Cryolite has been used
as a pesticide.
- The cryolite increases
the conductivity and consequently the electricity yield.
- Multiple applications
of Cryolite during the growing season significantly increase fluoride in
wines. Therefore, Cryolite application rate and timing
are critical
to ensure adequate insect control and minimize fluoride residues.
- The resultant alumina
(Al2O3) is dissolved in molten cryolite (Na3AlF6), forming an ionic and
electrically conductive solution. The aluminium produced is subsequently
alloyed depending on the required end-product.
- The anodic behavior of
metals in molten cryolite-alumina melts has been investigated mostly for
use as inert anodes for the Hall-Héroult process.
- Cryolite is the
principal mineral of the aluminium fluoride lpouP, and the only one to
be of any commercial importance.
