Impure `Ni + 4CO overset((60-80)^(@)C)rarr Ni (CO)_(4) overset(180^(@)C)rarr Ni +4CO`
The above process of purification of the metal is known as

A

Van-Arkel process

B

Pyrometallurgy

C

Mond process

D

Zone refining

Text Solution

Verified by Experts

The correct Answer is:
C
Ni is purified by Mond.s process in which impure nickel is treated with CO to form volatile complex called nickel tetracarbonyl. It decomposes to form pure nickel and CO at high temperature.
