Cobalt: The mineralogy of Cobalt - Mindat.org

Most widespread minerals containing Cobalt; This list of minerals containing Cobalt is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Cobalt mineral species.

Cobalt Facts and Physical Properties - thoughtco.com

Cobalt derived its name from German miners. They named cobalt ore after mischievous spirits called kobalds. Cobalt ores commonly contain the useful metals copper and nickel. The problem with cobalt ore is it usually contains arsenic as well. Attempts to smelt the copper and nickel typically failed and would often produce toxic arsenic oxide gases.
