Question:
Bayer's process is used for purifying
Bayer's process is used for purifying
Show Hint
Bayer's = Bauxite to Alumina. Hall-Heroult = Alumina to Aluminium.
Updated On: Jul 4, 2026
- Bauxite
- Alumina
- Aluminium
- Copper
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept Aluminium extraction is a two-stage process: refining the ore and then smelting the oxide.
Step 2: Meaning Bauxite is the primary ore of aluminium, containing impurities like iron oxide and silica.
Step 3: Analysis The Bayer's process involves dissolving the aluminium content of bauxite in caustic soda to separate it from insoluble red mud.
Step 4: Conclusion Therefore, Bayer's process is the standard method used for purifying Bauxite to produce pure alumina. Final Answer: (A)
