Jamshedpur : Samir VKamat, Outstanding Scientist & Director, Defence Materials Research Laboratory (DMRL) inaugurated the ‘Tungsten Extraction Pilot Plant’ at CSIR-National Metallurgical Laboratory ( NML) on Thursday.
Defence Research & Development Organization (DRDO) through Defence Metallurgical Research Laboratory (DMRL), Hyderabad has financed for setting-up of this pilot plant at CSIR-NML located at Nildih. The CSIR-NML ‘Tungsten Extraction Technology’ will be demonstrated in this pilot plant before its commercialisation by DRDO.
An official of NML said that Tungsten is a strategic metal and found critical application in defence, mining, communications and also in various sectors.
Globally, monopolistic world market is occupied by Chinese in the supply of tungsten and the annual demand of tungsten over 1500 MT in India is met through imports in general.
In order to make import substitution and partly self reliant in terms of annual domestic tungsten demand, particularly for defence applications, indigenous tungsten recycling technology becomes highly essential & important.
CSIR-NML in the recent past has already developed and successfully commercialized tungsten carbide scrap recycling technology.
The very much essence of commissioning of this pilot plant is to widen the scope of this technology in order to accommodate other varieties of tungsten bearing scraps.
