2018-8-5 Nickel refining Various processes are used to refine nickel matte. Fluid bed roasting and a chlorine-hydrogen reduction will produce high grade nickel oxides (95%+ nickel). Vapor processes, such as the carbonyl process, can be used to produce high purity nickel pellets. In this process, copper and precious metals remain as a

2017-12-28 Describe a method for refining nickel. Answer. Nickel is refined by Mond's process. In this process, nickel is heated in the presence of carbon monoxide to form nickel tetracarbonyl, which is a volatile complex. Then, the obtained nickel tetracarbonyl is decomposed by subjecting it to a higher temperature (450 - 470 K) to obtain pure nickel ...
