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! Huge amounts of energy would be needed to melt it.
