Describe a method for refining nickel

Describe a method for refining nickel Answer Nickel is refined by Mond's process In this process nickel is heated in the presence of carbon monoxide to form nickel tetracarbonyl which is a volatile complex Then the obtained nickel tetracarbonyl is decomposed by subjecting it to a higher temperature (450 - 470 K) to obtain pure nickel Get price
