Explanation:
Aluminium is the most abundant metal in the earth's crust. It does not occur in the free state as it is a reactive metal. Ores of aluminium are: Bauxite, Cryolite and Corundum. Bauxite is hydrated aluminium oxide having the formula \(Al _2 O _3 \cdot 2 H _2 O\)

Explanation:
Corundum is best known for its gem varieties, Ruby and Sapphire. Corundum is a very hard, tough, and stable mineral. Chemical formula of corundum is \(Al _2 O _3\)
