Solution
The correct option is A Vapour phase refining
The main process for extraction nickel in the pure form uses vapour phase refining.
In this process, nickel is heated in a stream of carbon monoxide forming a volatile complex, nickel tetracarbonyl.
Ni+4CO330−350k⟶Ni(CO)4
The carbonyl is heated to get pure metal.
Ni+(CO)4450−470k→Ni+4CO
