DescriptionRelation to MiningUsesCobalt (Co) is a bluish-gray, shiny, brittle metallic element. It has magnetic properties similar to iron. There are no significant minerals of cobalt. It is rare and obtained mostly through refining of nickel ore. It is used in super alloys for jet engines, chemicals magnets, and cemented carbides for cutting tools. Principal cobalt-producing countries include Democratic Republic of the Congo, Zambia, Canada, Cuba, Australia and Russia. The United States consumes about one-third of t

OverviewCharacteristicsCompoundsIsotopesHistoryOccurrenceProductionExtraction

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and p
