Mond Process

Name:
Mond Process
Detailed information:
Mixed ores, obtained from roasting crude ores, are heated from 50 to 80C in a stream of producer gas. Oxides other than nickel are reduced to the metallic state, whereas nickel forms nickel carbonyl [Ni(CO)₄], which passes off as a vapor. The vapor is subsequently resolved into carbon monoxide and free nickel.
