Summary: | Directed to a process for recovering nickel from an impure reducible nickel compound wherein an aqueous bath containing the compound, either dissolved or undissolved, is treated with a water-soluble sulfide and a reducing agent which may be carbon monoxide, hydrogen, sponge iron, iron carbonyl, zinc powder or aluminum powder, then heating the aqueous bath having a pH no lower than that of an aqueous solution saturated with carbon dioxide under carbonylation conditions to a temperature between about 100 DEG C. and 200 DEG C. under a carbon monoxide partial pressure of more than about 30 atmospheres to form substantially pure nickel carbonyl which is then recovered. |
