Solution

Oxide of Aluminum
Ore for extraction of Aluminum $(Al)$
1. It is the Bauxite ore, which is an impure oxide of Aluminum.
2. Aluminum $(Al)$ is extracted from the purification of this ore.
3. The purification process of Bauxite ore is known as Baeyer's process.
Chemical Formula of ore
Bauxite ore- ${Al}_{2} O_{3} . 2 H_{2} O$
Hence, the most common ore of the metal Aluminum from which the metal is extracted is Bauxite ore. Its chemical formula is ${Al}_{2} O_{3} . 2 H_{2} O$ .
