Home Gemstones Cryolite Value, Price, and Jewelry Information. By Joel E. Arem, Ph.D., FGA, International Gem Society. Typically colorless with a "sleepy" look, cryolite is rarely found in nature. Rough suitable for gem faceting is extremely scarce. However, the synthetic version of this mineral has many industrial uses.
L'invention concerne un procédé pour réguler la teneur en AlF3 dans des bains de cryolite pour la réduction de l'aluminium, la température du bain étant mesurée. Dans le but de créer un procédé très précis qui permette la réduction de l'aluminium à la température la plus basse possible, c'est-à-dire en économisant autant d'énergie que possible, la …
Based on recent survey work sponsored by the Geological Survey of Greenland, an attempt is made here to establish an appropriate background to the cryolite deposit at Ivigtut. The cryolite ore body occurs within the original top part of a stock of alkali granite which, during the younger time of the cratonic Gardar period, was emplaced into the older, folded …

Cryolite, Na 3[AlF 6], occurs naturally as a rare mineral. 1 Histori-cally, it was used as a source of aluminium but this has been superseded by bauxite (a mixture of the Al 2O 3 containing minerals boehmite, diaspore and gibbsite), largely because of the higher Al content of bauxite ( 50%) vs. cryolite (13%) and the scarcity of the latter.
Cryolite, colourless to white halide mineral, sodium aluminum fluoride (Na3AlF6). It occurs in a large deposit at Ivigtut, Greenland, and in small …
Cryolite ( Na 3 Al F 6, sodium hexafluoroaluminate) is an uncommon mineral identified with the once-large deposit at Ivittuut on the west coast of Greenland, mined commercially until 1987. Usually massive, coarsely granular. The rare crystals are equant and pseudocubic.
Cryolite occurs in syenite vein deposits (igneous rock which is quartz deficient) which had abundant amounts of fluorine. There are 13 other known mineral specimens that contain …
cryolite: [noun] a mineral consisting of a fluoride of sodium and aluminum found especially in Greenland usually in white cleavable masses and formerly used as a source of aluminum.
Crystal System: Tetragonal. Name: From the Greek χιώυ, snow, and λίθος, stone, in allusion to its appearance and similarity to cryolite (ice-stone). Type Locality: ⓘ Pit No. 69 (G.I.

The Mineral cryolite. Cryolite is an unusual mineral with an interesting history. It was commercially mined in large quantities in Greenland since the mid-1800's, and this one locality produced almost the entire source of collectors specimen. Cryolite's economic importance was as a flux for the production of aluminum, but its significance ...
Cryolite (Na 3 [AlF 6 ]), sodium hexafluoroaluminate) is an uncommon mineral identified with the once large deposit at Ivigtût on the west coast of Greenland, depleted by 1987. It was historically used as an ore of aluminium and later in the electrolytic processing of the aluminium-rich oxide ore bauxite (itself a combination of aluminium ...
