Geological Survey of India (GSI) has found promising concentration of vanadium in the palaeo-proterozoic carbonaceous phyllite rocks in the Depo and Tamang areas of Arunachal Pradesh’s Papum Pare district.

“Good prospects” of vanadium for a cumulative length of 15.5 km and an average thickness of 7m were found in the Deed, Saiya and Phop areas of Lower Subansiri district. Vanadium content was also found in the Pakro area of Pakke-Kesang district, Palin-Sangram in Kra Daadi, Kalamati in West Siang, Kalaktang in West Kameng and Kaying in Siang district.

Vanadium Deposits/Consumption

The largest deposits of vanadium are found in China, followed by Russia and South Africa.

India is a significant consumer of vanadium but is not a primary producer of the strategic metal.

India consumed 4% of about 84,000 metric tonnes of vanadium produced across the globe in 2017. China, which produces 57% of the world’s vanadium, consumed 44% of the metal.

About Vanadium Metal

  • Vanadium is a chemical element with the symbol ‘V’ and atomic number 23.
  • It is a hard, silvery-grey, malleable transition metal.
  • The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
  • Vanadium resists corrosion due to a protective film of oxide on the surface.


Most of the vanadium (about 80%) produced is used as ferrovanadium or as a steel additive. Mixed with aluminum in titanium alloys is used in jet engines and high speed air-frames, and steel alloys are used in axles, crankshafts, gears and other critical components. Vanadium alloys are also used in nuclear reactors because vanadium has low neutron-adsorption abilities and it does not deform in creeping under high temperatures.

Vanadium oxide (V2O5) is used as a catalyst in manufacturing sulfuric acid and maleic anhydride and in making ceramics. It is added to glass to produce green or blue tint. Glass coated with vanadium dioxide (VO2) can block infrared radiation at some specific temperature.

Apart from increasing fuel-efficiency in automotive and aviation industries due to its high strength-to-weight ratio, the metal forms the integral part of vanadium redox batteries that have the least ecological impact in energy storage.
