Vanadium Deposits in Arizona

Abstract: The occurrence of vanadium in Arizona has been documented since the early 1900s (Bulletin 115, AZ Bureau of Mines, U of AZ, September 1, 1921). Vanadate deposits occur throughout the State and the main vanadium mineral is vanadinite, a chloro-vanadate of lead, commonly associated with the oxidation of lead sulfides in sedimentary rocks. The historic Tiger Mine (Au-V-Pb-Zn-Mo-Cu-Ag) located in the Mammoth mining district in Pinal County produced vanadium pentaoxide during the war years. Uranium and vanadium was mined in the 1950s in the Salt Wash Member of the Upper Jurassic Morrison Formation along the perimeter of the Carrizo Mountains in Apache County (Zona No.1 Mine, Chenoweth, 1990). Although Arizona has not been an important producer of vanadium in the past, it has the potential to become a producer should the demand for this metal increases in the coming years. While the use of vanadium as an alloy in the steel industry is the largest application for this metal, growth in demand is expected to come from the renewable energy industry in the form of vanadium flow batteries used for energy storage. This presentation describes the vanadium occurrences in the Zn- PbMo-V deposits in the Miami-Globe, Dripping Springs and Mammoth districts of Arizona.
