Mineral technology laboratories are located at Hyderabad and
Nagpur. The laboratories are engaged in carrying out investigations on the feasibility of recovering uranium and
other elements from the ore.
Facilities exist for carrying out physical beneficiation and hydrometallurgy.
In addition to conventional techniques, the mineral technology laboratory
at Hyderabad has been in the forefront of using bacterially-aided
leaching technique.
This technology provides data on
(i) isolation
and identification of different algae and bacteria in the uranium
ore,
(ii) their role in the genesis of uranium mineralisation and
(iii) microbiology based leachability of uranium and its associated
metals.
All the laboratories have been provided with crushers, grinders,
equipment necessary for gravity concentration, flotation, magnetic
separation and electrical separations. They also have facilities
for carrying out investigations on the extraction of uranium from
ores, purification by ion exchange and solvent extraction techniques
and precipitation of uranium as diuranate. Over the years, the
laboratory has contributed significantly in Recovery
of niobium and tantalum minerals from the pegmatitic eluvium.
Recovery
of xenotime from the riverine placers.
Beneficiation
of pyrochlore from carbonatitic soils.
Development
of flow sheet for recovering wolframite from granite of Degana, Rajasthan.
Development
of flow sheet for improvement in recovery of beach sand minerals
at the OSCOM Project (Orissa).
Pilot
plant extraction including biochemical leaching of uranium ores at
field sites.
Removal
of (a) H2S from the effluents of heavy water plants and
(b) cyanide in the gold tailings nitrates from the effluents of Nuclear
Fuel Complex, Hyderabad.
