conventional uranium ore deposits are limited and lean in tenor. The indigenous supply of uranium to the power reactors of the country is met mainly from the uranium ore deposits located in East Singhbhum of Jharkhand milled at Jaduguda and Turamdih. The rising demand for nuclear power has naturally necessitated increased supplies of uranium.

A comparison of the uranium recovery from low-grade ore by ...

uranium recovery. During bioleaching of uranium, also other metals (including rare metals) recovery was reported (Drewniak, 2014). The economy of uranium recovery from these ores is rather low. Bioleaching techniques could be economic on an industrial scale only when using material containing above 0.03% U 3 O 8 (Rewerski et al., 2013).

NRC: Uranium Recovery

As the precursor to the nuclear fuel cycle, uranium recovery focuses on extracting (or mining) natural uranium ore from the Earth and concentrating (or milling) that ore. These recovery operations produce a product, called " yellowcake," which is then transported to a fuel cycle facility .

Uranium ore - Wikipedia

Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans.
