Mond process

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890,^[1] to extract and purify nickel. The process was used commercially before the end of the 19th century,^[2] and particularly by the International Nickel Company in the Sudbury Basin.^[3] This process converts nickel oxides into nickel metal with very high purity being attainable in just a single step.
