Environmental Guidelines for Nickel Smelting and 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 pyrophoric residue requiring separate treatment. Electrical cells equipped with inert

Nickel: smelting, producing-Metalpedia

In the process, nickel is reacted with carbon monoxide at around 40–80 °C to form nickel carbonyl in the presence of a sulfur catalyst. Iron gives iron pentacarbonyl, too, but this reaction is slow. If necessary, the nickel may be separated by distillation.

In the electrolytic refining process, the nickel is unloaded onto pure nickel cathodes from sulfate or chloride solutions in electrolytic cells. In carbonyl refining, carbon monoxide is allowed to pass through the matte, in order to produce nickel and iron carbonyls [Ni (CO) 4 and Fe (CO) 5 ].
