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 extraction of aluminum and fluoride decreases from 20.6% and 5.25% to 0.11% and 0.48% respectively, as the calcination temperature increases from 533 K to 673 K.
