HI HERE IS YOUR 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) to obtain nickel metal.

NI + 4CO2------------->NI(co)4

NI(CO)4--------------------->NI +CO
