In the sulfidic removal process of copper, these precious metals enter the copper sulfide residue and are recovered in copper smelting. Carbonyl Nickel Process. It is a process for preparing metal nickel and its products by using the formation of carbonyl nickel [N(iCO) 4] and its decomposition reaction (Ni + 4CO=Ni(CO) 4) (see carbonyl process).
