Final answer:
The main ore of Aluminum is bauxite, which is composed of impurities such as iron oxides, silicon dioxide, and titanium dioxide. It is obtained through the Bayer Process and electrolysis.
Step-by-step explanation:
The main ore of Aluminum (Al) is bauxite. Bauxite is essentially an impure aluminum oxide and is the most common ore used for the extraction of aluminum.
It is composed of impurities such as iron oxides, silicon dioxide, and titanium dioxide.
To extract aluminum from bauxite, the ore is first converted into pure aluminum oxide using the Bayer Process. Then, electrolysis is used to extract aluminum from the aluminum oxide in a solution of molten cryolite.
