It is ferromagnetic up to 1,121 вЊ (2,050 вЏ, the highest known Curie point of any metal or alloy) and may find application where magnetic properties are needed at elevated temperatures.Д¬obalt is one of the three metals that are ferromagnetic at room temperature. Two allotropes are known: the hexagonal close-packed structure, stable below 417 вЊ (783 вЏ), and the face-centred cubic, stable at high temperatures. Polished cobalt is silver-white with a faint bluish tinge.

(For additional information on the mining, refining, and recovery of cobalt, see cobalt processing.) The largest producer of refined cobalt, however, was China, which imported vast additional amounts of cobalt mineral resources from the DRC. By the second decade of the 21st century, the Democratic Republic of the Congo (DRC), China, Canada, and Russia were the worldвЂ™s leading producers of mined cobalt. Complex processing is required to concentrate and extract cobalt from these ores. Rather, it is often recovered as a by-product from the mining of ores of iron, nickel, copper, silver, manganese, zinc, and arsenic, which contain traces of cobalt. With few exceptions, cobalt ore is not usually mined for the cobalt content. Courtesy of the Field Museum of Natural History, Chicago, photograph, John H.
