Abstract

Experiments/testworks were carried out on Degana tungsten ore by various R & D organizations to recover the strategic mineral wolframite. Process flowsheet developed after tests on the dump ore assaying 0·151% WO3 is being tried on a very small scale till the 150 tpd pilot beneficiation plant is commissioned. Tungsten bearing granite samples were also found amenable to physical benefication. Hence 168 Mt granitic resources analysing 0·08% WO3 has ushered a hope for large scale exploitation subject to detailed exploration. By-product recovery of lithium, caesium, rubidium and some other trace elements, if feasible, will be of added advantage.
