Vanadium - Assignment Point

Vanadium

  • chemical element with the symbol V.
  • Vanadium is a scarce element, hard, silvery grey, ductile and malleable transition metal with good structural strength.
    • The Transition metals are all the elements in groups 3–12 of the periodic table. These are superior conductors of heat as well as electricity.

Ores

  • Patronite, roscoelite, vanadinite and carnotite.

Uses of Vanadium

  • The major use of Vanadium, primarily as an alloying element in the Iron & Steel Industry and to some extent as a stabiliser in titanium and aluminium alloys used in the aerospace Industry.
    • The Modern applications of vanadium include its use as vanadium secondary batteries for power plants and rechargeable Vanadium Redox Battery for commercial applications.
    • Vanadium alloys are also used in nuclear reactors because of vanadium’s low neutron-absorbing properties.

Vanadium Reserves in Arunachal Pradesh

  • The Concentrations of the vanadium have been found in the palaeo­proterozoic (era) carbonaceous phyllite rocks in the Depo and Tamang areas of Papum Pare district in Arunachal Pradesh.
    • The Phyllite is a fine-grained metamorphic rock formed by the recrystallization of fine-grained, parent sedimentary rocks, such as mudstones or shales.
    • The Sedimentary rocks containing significant enrichment in organic matter over average sediments are called carbonaceous sedimentary rocks.
  • There are other potential sites in various districts in Arunachal Pradesh.
  • This is the first report of a primary deposit of vanadium in Northeastern state in India.

Current Scenario

  • India is a significant consumer of vanadium, but is not a primary producer of the strategic metal.
    • According to data provided by the Geological Survey of India, India consumed 4 per cent of total global production of Vanadium in the year 2017.
  • It is recovered as a by-product from the slag of processed vanadiferous magnetite (iron) ores.
    • The Slag is a glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.
