Which of the following shows an incorrect method of refining?
- Zinc : Liquation
- Copper : Electrolysis
- Titanium : Van Arkel Method
- Nickel : Mond’s Process
The Correct Option is A
Solution and Explanation
Zinc is refined by distillation methods used for metal having low boiling points.
So, the correct option is (A): Zinc : Liquation.

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
