Critical Minerals of Arkansas
Vanadium (V)
During the 1950’s while searching for radioactive minerals, vanadium was discovered to be
in economic quantities at Potash Sulphur Spring igneous complex, Garland County, and
Magnet Cove igneous complex, Hot Spring County.
In 1962, Union Carbide delineated several ore-grade deposits in highly altered Paleozoic
rocks from the contact metamorphic zone around Potash Sulphur Springs complex.
The Christy deposit at the adjacent Magnet Cove igneous complex also has ore-grade
material occurring in recrystallized and altered Arkansas Novaculite.
The principal ore minerals are vanadiferous goethite with some minor amounts of
vanadium-bearing brookite.
Approximately 4.8 million tons of 1.2% V2O5 has been processed from Arkansas ore.
The last production of V2O5 was in 1990.
The T deposit and Spaulding deposit at Potash Sulphur Springs contain ore grade rock that
has not been mined to date.
Minerals associated with the vanadium are titanium, niobium, molybdenum, with lesser
amounts of tantalum, uranium, complex rare earth oxides and fluorine.
