How Nickel is Produced

Primary nickel is produced and used in the form of ferro-nickel, nickel oxides and other chemicals, and as more or less pure nickel metal. Nickel is also readily recycled from many of its applications, and large tonnages of secondary or "scrap" nickel are used to supplement newly mined metal.

Mond process - Wikipedia

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, to extract and purify nickel.The process was used commercially before the end of the 19th century. This process converts nickel oxides into pure nickel. This process involves the fact that carbon monoxide combines with nickel readily and reversibly to give nickel carbonyl.
