A recent exploration by GSI has found reserves of Vanadium in northeaster state Arunachal Pradesh. Vanadium Deposits found in India
- The GSI is an attached office to the Union Ministry of Mines.
- GSI is Geological Survey of India
- A 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.
- 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.
- 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.
