Extraction of Aluminium by Electrolysis

Aluminum is extracted from aluminum oxide by a process called electrolysis. First of all, aluminum oxide needs to be in molten form to extract the aluminum ions. Aluminum oxide, however, has a high melting point. Therefore, aluminum oxide is dissolved in molten cryolite.

(a) How is aluminium extracted from alumina?(b) Give …

a) it is extracted by electrolysis. The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite - another aluminium compound.The alumina is dissolved in a mixture of molten cryolite and fluorspar which lowers the melting point. It is then electrolysed in a rectangular steel tank with carbon lining, which serves as ...
