Along with carnotite and roscoelite, vanadinite is one of the main industrial ores of the element vanadium, which can be extracted by sodium vanadate ( NaVO 3 ).

The mine was initially called " Smith's Carnotite Mine " ( a similar uranium-bearing mineral ) and in September 1906 Mawson proposed the name " Radium Hill ".

Some of the carnotite, the uranium-bearing mineral he pulled out of the earth, ended up in the lab of Madame Marie Curie, he said, via his buyer in Pennsylvania.

The Carnotite sands in Colorado provide some of the element, but richer ores are found in the Congo and the area of the Great Bear Lake and the Great Slave Lake of northwestern Canada.

Regular production of uranium-bearing ore in the United States began in 1898 with the mining of carnotite-bearing sandstones of the Colorado Plateau in Colorado and Utah, for their vanadium content.
16.
Although no more than a trace of radium was present in the ore, newly discovered medical applications had made radium worth $ 100 per milligram, making the radium in the carnotite ore worth much more than the vanadium or uranium.

"' Carnotite "'is a potassium uranium vanadate radioactive mineral with chemical formula : H 2 O . The water content can vary and small amounts of calcium, barium, magnesium, iron, and sodium are often present.
18.
While uranium is used primarily for nuclear power, uranium mining had its roots in the production of uranium-bearing ore in 1898 with the mining of carnotite-bearing sandstones of the Colorado Plateau in Colorado and Utah, for their vanadium content.
19.
Once carnotite was known to contain radium, prospectors rushed to the Colorado Plateau of southwest Colorado and adjacent southeast Utah, and found carnotite-bearing sandstones of the Jurassic Morrison Formation in Montrose County that had become the world s largest supplier of radium.
