But in 1884, American and French chemists learned to dissolve alumina in molten cryolite, then to inexpensively extract metallic aluminum by electrolysis. This discovery, patented as the Hall-Héroult process, finally made aluminum affordable.

The selection of the process depends upon the availability and cost of raw materials. The simplest and most common method of obtaining synthetic cryolite is by reacting hydrofluoric acid with soda ash and alumina hydrate. Hydrofluoric acid is produced by reacting acid grade fluorspar with sulphuric acid and by-product gypsum is obtained in this ...

What are the Cryolite Ores? Cryolite is a salt of sodium aluminium hexafluoride. It is represented as Na3AlF6. It consists of Aluminium, Sodium and Fluorine. It can be synthesized by the given reaction. H2SiF6 + 6 NH3 + 2H20 → 6NH4F + SiO2. 6NH4F + 3NaOH + Al (OH)3 → Na3AlF6+ 6NH3 + 6 H2O. Cryolite ores are the chief ore of aluminium.
