    Ianthinite, rare uranium oxide mineral discovered in Mahbubnagar district - The Times of India

    HYDERABAD: The city-based Atomic Minerals Directorate has found deposits of Ianthinite, a rare mineral of uranium, at Akkavaram village of Atchampet mandal in Mahbubnagar district of Andhra Pradesh. Though Ianthinite has been known to science for the last 90 years it is for the first time that the uranium mineral is discovered in India.

    Ianthinite is a type of uranium oxide mineral that contains two types of uranium (U6+ and U4+). The discovery of Ianthinite in Atchampet mandal abutting the Nallamala forests may help geologists to explore more uranium resources in the region. Ianthinite has been discovered so far only from eight countries including the USA, Germany, and France. India now joins the elite club after the Akkavaram discovery.

    A team of researchers from Atomic Minerals Directorate comprising PS Parihar, SK Srivastava, Yamuna Singh, KK Parashar, PV Ramesh Babu, and R Viswanathan found Ianthinite from underneath Mahbubnagar granite deposits at Akkavaram village. Ianthinite was found in the form of tiny grains along with uraninite and uranophane, two radioactive minerals of uranium.

    Ianthinite was discovered in early 1920s from a uranium mine in Congo. But its presence in India was not known till the AMD team discovered it in Mahbubnagar district recently. The researchers published their finding in the latest issue of the Journal of Earth System Science (JESS) of the Indian Academy of Science.

    From geological point of view, Akkavaram falls in Srisailam sub-basin of Cuddapah basin, which is famous for significant presence of uranium resources. The AMD team found uranium mineralization in granitoids (a type of granite) and sandstone and grit in the area.

    The granitoids and sandstone/grit showed presence of triuranium octoxide (U3O8) up to 0.25 per cent and 0.031 per cent respectively. The researchers also found other minerals like anatase, rutile, microcline, biotite, and quartz from Akkavaram.

    "Ianthinite plays a key role in understanding the sequence of formation of complex assemblage of uranyl minerals, although its occurrence in nature is very rare. Its rarity in nature is mainly due to its instability in the presence of oxygen," the team pointed out in their research publication.

    Largest uranium reserves found in India

    Srikumar Banerjee, head of the Atomic Energy Commission, said a four-year long survey had indicated that the Tumalapalli mine near the state capital Hyderabad, which is scheduled to begin operating by late 2011, could provide up to 150,000 tons of uranium.
    "It's confirmed that the mine has 49,000 tons and there are indications that the total quantity could be three times that amount" Mr Banerjee said on a visit to a nuclear plant in the western state of Rajasthan on Monday.
    If that is the case, it will become the largest uranium mine in the world, he added.
    But Department of Atomic Energy officials warned that the mineral, which is refined into nuclear fuel to produce energy and power, is not "high but low-grade uranium".
    India has eagerly been seeking new uranium supplies worldwide to fuel its atomic plants for desperately-needed power to sustain high economic growth.

    Over the past three years it has concluded supply deals with France, Kazakhstan and Russia after securing a special exemption in 2008 from the 46-member Nuclear Suppliers Group that governs global nuclear trade to conduct civil nuclear commerce.
    The special waiver permits India to procure atomic reactors and fuel from overseas in return for international inspections of 14 of its 22 atomic reactors without signing the Nuclear Non-Proliferation Treaty, the NPT.
    The remaining eight military reactors and associated facilities would not be subject to International Atomic Energy Agency examination.
    India's rapidly growing economy, which is heavily dependent on coal, remains desperately short of power, getting less than three per cent of its energy from nuclear plants.
    It hopes to substantially increase this output to around 30 per cent by 2050 by erecting 30 atomic reactors and the domestic uranium find would not only boost its plans but also help reduce costs.
