Outline the principle of the method used for refining of Nickel. – InterviewSolution

1.	Outline the principle of the method used for refining of Nickel.
Answer» SOLUTION :NICKEL is refined by vapour phase refining (Mond.s PROCESS) `{:(Ni+4CO overset(330-350K)(to)Ni(CO)_(4)),("Nickel carbonyl "):}` Nickel carbonyl is SUBJECTED to higher temperature when it decomposes to give pure nickel. `Ni(CO)_(4) overset(450-470K)(to) Ni + 4CO`.
