Charles Martin Hall: Electrolysis of Aluminium - Cryolite

The aluminium is then dissolved in molten cryolite - this lowers the melting point, which reduces the total costs of the process. Electricity is passed through and electrolysis begins. Electrolysis is the decomposition of a compound using electricity. When dissolved, the aluminium ions and oxide ions in the alumina can move.

what is cryolite's purpose in the extraction of aluminum ...

Cryolite itself melts below 900°C (1173 Kelvin), and it can dissolve the aluminium oxides sufficiently well to allow easy extraction of the aluminium by electrolysis. Considerable energy is still required for both heating the materials and the electrolysis, but it is much more energy-efficient than melting the oxides themselves.
