Named after the town of Kamoto, and the Kamoto mine in the Democratic Republic of the Congo where the mineral gets its type locality. Kamotoite is a rare mineral that forms in oxidized uranium-bearing copper-cobalt deposits. It can be found in additional localities in Switzerland, Norway, Germany, the Czech Republic, and Canada. Kamotoite is radioactive.

Named for Dr. Robert Anthony Kampf of the Los Angeles County museum of Natural History in California, USA, for his contributions to the study of minerals. Found only at the Esquire No.1, the type locality, and Esquire No.7 claims near Big Creek-Rush Creek in California, USA. It occurs there as a rock forming mineral in a quartz-sanbornite gneiss where it forms as light blue-gray, irregular, cleavable masses.

Named in honor of the supplier of the first specimens, Norwegian mineral collector Erling Kamphaug.

Localities for Kamphaugite include in Norway, Italy, Kazakhstan, Hungary, Russia, South Africa, Canada, the United States, and Australia.
