Nickel 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. The mixture of nickel carbonyl and Syngas is heated to 220– 250 °C, resulting in decomposition back to nickel …

Lateritic nickel ore deposits - Wikipedia

Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
