New Caledonia: open-pit nickel mineNickel and its extraction - SlideShare,03-05-2018· This process has three steps: 1. Nickel oxide reacts with Syngas at 200 °C to give nickel, together with impurities including iron and cobalt. NiO(s) + H2(g) → Ni(s) + H2O(g) 2. The impure nickel reacts with carbon monoxide at 50–60 °C to form the gas nickel carbonyl, leaving the impurities as solids. Ni(s) + 4 CO(g) → Ni(CO)4(g) 3.Nickel - Extraction and Purification - Mond Process,Nickel is re-obtained from the nickel carbonyl by one of two processes.
