Thorium is also a potential nuclear fuel of the future. Exposure to thorium is encountered in the mining and milling of monazite (thorium ore) and at various other stages in the thorium industry. In order to assess the handling hazards of thorium minerals and compounds, it is important to study this element in the normal environment.

The export of monazite was not allowed because it is primarily used to produce uranium and thorium, which are used as fuels for nuclear plants. The Indian Minerals Year Book estimates that Indias coastline has a deposit of 10.7 million tonnes of monazite, from which 846,477 tonnes of thorium can be extracted. Indiscriminate mining

India has been processing monazite, and enough thorium has been stockpiled for the future use. Indias Uranium imports since 2008 Ever since India accessed to the global nuclear fuel market in 2008, the country has been one of the major nuclear fuel buyers.
mining and milling for recovery of thorium will be rst reviewed briey. 2.1 Thorium Mining and Milling Thorium, in India, occurs in the form of monazite along with other heavy minerals from the beach sand. The monazite content of the beach sand varies from 0.1 to 338 K. Raj et al.
Uranium and Thorium processing from uranium ore and monazite as by product of other mining still Measurements for the Development of a Simulated 2012 4 25 uranium, thorium, radium and potassium) were investigated, including zircon sand, litter, roofing tiles, ice melt and fertilizer among others.
India's three stage nuclear power programme was formulated by Homi Bhabha in the 1950s to secure the countrys long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India. The ultimate focus of the programme is on enabling the thorium reserves of India to be
significant enough to result in occupational and environmental radiation exposures during their mining, milling and chemical processing for the extraction of the rare earth elements and compounds. Depending on the monazite concentration in the raw sand, radiation exposures of the order of 0.131.00 man183;mSv per tonne
Monazite. Monazite is a phosphate mineral [(Ce, La, Nd, Th)PO4], the major commercial source of Ce. Occurring as small heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite contains up to 27 wt.

Medallion is looking to derive REEs from monazite, which occurs in mineral sands around the world, and is most often associated with titanium and zircon mining. By sourcing monazite supplies from
Monazite (chiefly phosphates of various rare earth elements) is the most important commercial source of thorium because it occurs in large deposits worldwide, principally in India, South Africa, Brazil, Australia, and Malaysia. It contains around 2.5% thorium on average, although some deposits may contain up to 20%.
India's three stage nuclear power programme Monazite powder, a rare earth and thorium phosphate mineral , is the primary source of the world's thorium The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements.
