 | | Cobalt occurs in the mineral cobaltite, smaltite, and erythrite, and is often associated with nickel, silver, lead, copper, and iron ores, from which it is most frequently obtained as a by-product. |
 | | Cobalt is also used in other magnet steels and stainless steels, and in alloys used in jet turbines and gas turbine generators. |
 | | Cobalt molybdenum alloys are used for the desulfurization of high-sulfur bituminous coal, and cobalt iron alloys in the hydrocracking of crude oil shale and in coal liquefaction. |
