The metal refined by Van Arkel method is
The metal refined by Van Arkel method is
Ni
Zr
Cu
Sn
The Correct Option is B
Solution and Explanation
The metal refined by the Van Arkel method is Zr (Zirconium).
The Van Arkel method, also known as the iodide process, is a technique used for the purification of certain metals, including zirconium. In this method, the metal is converted into a volatile metal iodide, which is then decomposed to obtain pure metal. The Van Arkel method is commonly used for the purification and production of high-purity zirconium metal.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
