- \(TiO_2\)
- \(Al_2O_3\)
- \(ZrO_2\)
- \(SiO_2\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
The Bayer process is used to extract alumina from bauxite ore.
Step 1: Bauxite is an ore of aluminium.
Step 2: It contains hydrated aluminium oxide along with impurities.
Step 3: In the Bayer process, bauxite is treated with sodium hydroxide to dissolve alumina.
Step 4: Alumina is then precipitated and calcined to obtain: \[ Al_2O_3 \] Therefore, Bayer process is used to produce: \[ \boxed{Al_2O_3} \]
