REFINING: 1.MOND PROCESS The purest metal is obtained from nickel oxide by the Mond process, which achieves a purity of greater than 99.99%. 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.

Purification of nickel oxides to obtain the purest metal is performed via the Mond process, which increases the nickel concentrate to greater than 99.99% purity. This process was patented by L. Mond and has been in industrial use since before the beginning of the 20th century. In the process, nickel is reacted with carbon monoxide at around 40–80 °C to form nickel carbonyl in the presence ...
