Extraction of Aluminium

Extraction of Aluminium

+

Extraction of aluminium. Aluminium is extracted from it's ore by electrolysis. The electrolyte has to be molten ore, if a solution was used (as in the extraction of copper) hydrogen gas would be produced instead of the pure metal. The next problem lies in that aluminium ore, bauxite, has a very high melting point over 2000 degrees Celsius!
