Which of the following is the chief ore of aluminium?
Answer & explanation
Correct answer: option 2
The correct answer is option 2. Bauxite.
The primary source of aluminum is bauxite. Bauxite is made up of hydrated iron oxide and hydrated aluminum oxide and has the chemical formula Al2O3.2H2O. An further source of aluminum is kaolinite, although it is less common than bauxite and requires more effort and money to extract the metal.
