US4053375A - Process for recovery of alumina-cryolite ...
Alumina-cryolite waste from aluminum pot lines is subjected to oxidation in a fluidized bed reactor to remove carbon and organic contamination. Agglomeration of the alumina-cryolite product occurs in the fluidized bed and a pellet product suitable for return to the aluminum pot lines is produced.
Cryolite - Wikipedia
Cryolite occurs as glassy, colorless, white-reddish to gray-black prismatic monoclinic crystals. It has a Mohs hardness of 2.5 to 3 and a specific gravity of about 2.95 to 3.0. It is translucent to transparent with a very low refractive index of about 1.34, which is very close to that of water; thus if immersed in water, cryolite becomes essentially invisible.

Recovery of carbon rich material:-Recycling of spent pot ...
Abstract. Spent pot lining (SPL) is a carbon rich material generated during primary aluminium smelting process. The major constituents of SPL are carbon (40–50%), fluoride (10–18%), aluminium (10–13%), cyanide (700–4500 ppm) and sodium (12–16%) along with other metals like calcium, iron, lithium, titanium and magnesium in trace amounts.
Cryolite - an overview | ScienceDirect Topics
There is general agreement that molten cryolite is completely ionised to sodium ions and hexafluoroaluminate ions: [3.6] N a 3 Al F 6 = 3 N a + + Al F 6 3 −. Also it is well established that the hexafluoroaluminate anion dissociates further: [3.7] Al F 6 3 − = Al F 4 − + 2 F −. At the cryolite composition the anion is about 30% dissociated.
