Arunachal Pradesh likely to become India’s prime producer of Vanadium 

Part of: GS Prelims and GS-III – Economy; Sci & Tech

In news 

  • Arunachal Pradesh is likely to become India’s prime producer of vanadium.

Key takeaways

  • The largest deposits of vanadium in the world are in China, followed by Russia and South Africa.
  • China, which produces 57% of the world’s vanadium, consumed 44% of the metal in 2017.
  • India is a significant consumer of vanadium, but is not a primary producer of the strategic metal.
  • According to data provided by the GSI, India consumed 4% of about 84,000 tonnes of vanadium produced across the globe in 2017.
  • The Geological Survey of India (GSI) found promising concentrations of vanadium in the palaeo-proterozoic carbonaceous phyllite rocks in the Depo and Tamang areas of Papum Pare district in Arunachal Pradesh.
  • This was the first report of a primary deposit of vanadium in India, with an average grade of 0.76% V2O5 [vanadium pentoxide].
  • Vanadium mineralisation in Arunachal Pradesh is geologically similar to the “stone coal” vanadium deposits of China hosted in carbonaceous shale. 
  • This high vanadium content is associated with graphite, with a fixed carbon content of up to 16%.

Important value additions

  • 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. It is recovered as a by-product from the slag collected from the processing of vanadiferous magnetite ores (iron ore).
  • Vanadium is a high-value metal used in strengthening steel and titanium.
