Mond process for refining of Nickel is based on the principle that nickel is heated in the presence of carbon monoxide to form nickel tetracarbonyl, which is a volatile complex. Final purification of nickel oxides is performed via the Mond process, which increases the nickel concentrate to greater than 99.99% purity [25]. On moderate heating, such as contact with a hot glass surface, Ni(CO) 4 decomposes back to carbon monoxide and nickel metal. Thermal decomposition commences near 180 °C and increases at higher temperature. Nickel is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. The first step converts Ni(s) into nickel tetracarbonyl, Ni(CO)4, leaving impurities behind. The nickel oxide and impurities react with the hydrogen gas to form an impure solid nickel: Next, the carbon monoxide will react with the impure nickel.
