In 1890 Mond, Langer, and Quinke discovered that the direct combination of
nickel and carbon monoxide produced tetracarbonylnickel(0), [Ni(CO)4], a
reaction that is used in the Mond process for purifying nickel (Box 22.1): 50C,

Ni(CO)4 -» Ni + 4CO (150-220°C) This is known as the Mond process and used
in Ni smelting for about a century. Reduction Hydrogen is usually used as the
reducing agent, but sometimes, active metals such as K, Na, Mg, Zn, Cd. etc. can

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.[34

Chemistry and Chemical Reactivity
The Mond process, as it is now known, was the preferred procedure to obtain
pure nickel for the first half of the 20th century. Nickel is unique among metals in
its facile reaction with CO, but many other transition metal carbonyl compounds
are ...

The first step of the Mond process involves equilibrating impure nickel with CO(g)
and Ni(CO)4(g) at about 50°C. The purpose of this step is to convert as much
nickel as possible into the gas phase. Calculate the equilibrium constant for the ...
