The reaction at cathode is : 2 A l 3 + + 6 e − → 2 A l Thus pure aluminium metal is formed at the cathode. The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell.

Natriumhexafluoroaluminate [German] Aluminum sodium fluoride (Na3AlF6) Aluminum sodium hexafluoride (AlNa3F6) Aluminum trisodium hexafluoride. © Jeff Weissman / Photographic Guide to Mineral Species, Mouse 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 oxide minerals such as gibbsite, boehmite and diaspore). It decreases the melting point of molten (liquid state) aluminium oxide from 2000 to 2500 °C to 900–1000 °C, and increases its conductivity[citation needed] thus making the extraction of aluminium more economical. Pure cryolite itself melts at 1012 °C (1285 K), and it can dissolve the aluminium oxides sufficiently well to allow easy extraction of the aluminium by electrolysis. 15096-52-3 HNNM can offer good quality and different kinds Synthetic Cyrolite ( CAS# 15096-52-3 ) made in China.
