Answer 1

Explanation:

it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite - another aluminum compound. The aluminum oxide has too high a melting point to electrolyse on its own. The usual aluminum ore is bauxiteA soft, silvery-white, corrosion-resistant metal. It is the most abundant metal in the earth’s crust as it makes up 8% of the crust and it is the third most abundant element after oxygen and silicon. Bauxite ore (Al2O3.xH2O) is the major source of aluminium till date which is a mixture of hydrated aluminium oxide.

Aluminium can also be recovered from cryolite (Na3AlF6) and alunite. It is also found in gemstones such as garnet, topaz and chrysoberyl. The chemical symbol of this metal is Al. In the boron group with symbol Al, aluminium is a chemical element and is the most commonly used non-ferrous metal.

Answer 2

Explanation:

$\huge \underline { \orange{\bold{Answer :-}}}$

Aluminum is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic.Instead, it is extracted by electrolysis.

Steps :-

☘️ The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite - another aluminum compound.

☘️ The aluminum oxide has too high a melting point to electrolyse on its own. The usual aluminum ore is bauxite. Bauxite is essentially an impure aluminum oxide. The major impurities include iron oxides, silicon dioxide and titanium dioxide.
