Arunachal Pradesh could be India’s prime producer of vanadium.
[Vanadium - High-value metal used to strengthen steel and titanium.]
In India, Vanadium is recovered as a by-product from the slag collected from the processing of vanadiferous magnetite ores (iron ore).
But now promising concentrations of vanadium has been found in the palaeo-proterozoic carbonaceous phyllite rocks in the Depo and Tamang areas of 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).
Exploration is being carried out by Geological Survey of India (GSI).
Vanadium mineralisation in Arunachal Pradesh is geologically similar to the “stone coal” vanadium deposits of China in carbonaceous shale.
This high vanadium content is associated with graphite with fixed carbon content of up to 16%.
Vanadium
Vanadium in its pure form is a soft, grey and ductile element which
It is primarily derived from mined iron ore, carbonaceous shale or phyllites and steel slag.
Vanadium alloys are durable in extreme temperature and environments, and are corrosion-resistant.
It increases the fuel-efficiency in automotive and aviation industries due to its high strength-to-weight ratio.
It forms the integral part of vanadium redox batteries that have the least ecological impact in energy storage.
