Question

Zirconium is refined by ..................

• A. Liquation process
• B. Mond process
• C. Van Arkel method
• D. Electrolytic refining process

Hint:

The Van Arkel method is a process used to refine metals like zirconium by converting them into volatile compounds and then decomposing these compounds to obtain pure metal.

Answer 1

The Correct Option is C

Step 1: Understanding the refining methods.
Zirconium is refined using the Van Arkel method, which involves the formation of a volatile compound of zirconium, followed by its decomposition to yield pure zirconium metal.

Step 2: Analyzing the options.
(A) Liquation process: This process is used for separating metals like tin and lead but is not used for zirconium.
(B) Mond process: This process is used for refining nickel, not zirconium.
(C) Van Arkel method: This is the correct method for refining zirconium.
(D) Electrolytic refining process: This process is used for metals like copper but is not used for zirconium.

Step 3: Conclusion.
The correct answer is (C) Van Arkel method.
