Nickel - Extraction and Purification - Mond Process. 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. This process was patented by L. Mond and has been in industrial use since before the beginning of the 20th century.
Mond process is a technique to extract and purify nickel. This process converts nickel oxides into pure nickel. This process makes use of the fact that carbon monoxide complexes with nickel readily and reversibly to give nickel carbonyl.
