CO forms a volatile compound with Ni, Nickel carbonyl, under mild conditions(330-350K).  Impurities like iron and cobalt do not react under these conditions.  Nickel carbonyl being a gas is easily separated from solid impurities.  Ni is recovered as nickel carbonyl is easily decomposed by heating at 450-470K.
