Brazil's uranium resources occur in a number of geological environments and, consequently, belong to several deposit types, some of them hosted near the surface. In addition to known resources, there is a high potential for further discovery of uranium deposits. Brazil has been producing uranium since 1982.
The project consists basically in the mining and milling of uranium in the municipality of Caetite, Bahia state, Brazil. The method of uranium extraction is open-pit mining and the milling process is lixiviation in piles. All mined uranium is to be used domestically, after conversion and enrichment abroad (Canada and Netherlands, respectively).

The primary use for uranium obtained from mining is in fuel for nuclear reactors. Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, Kazakhstan, and Canada. To date, high-grade deposits are only found in the Athabasca Basin region of Canada.
Nuclear energy accounts for about 3% of Brazil's electricity. It is produced by two pressurized water reactor reactors at Angra, which is the country's sole nuclear power plant.Construction of a third reactor begun on 1 June 2010, but it is currently stalled. The sole Brazilian company in charge of nuclear energy production is Eletronuclear. Uranium exploration, production and export in Brazil ...
Owing to its property of being easily fissioned it is used by nuclear power plants. Uranium was formed at the time of the creation of the earth and is found in rocks all over the world. Rocks containing lots of uranium are called uranium ore, or pitch-blende. Uranium, present in abundance, is .
Apr 12, 2019· A minimum mineable uranium reserve necessary to support such a process facility is estimated at 22 million pounds of eU3O8 [8,462 t U]. The concept is that the mining of a number of satellite uranium ore bodies, controlled by different owners, would provide uranium ore feed to the central milling facility.
T his chapter presents a discussion of impacts of uranium mining and processing operations on air quality, soil, surface water and groundwater, and biota. Much is already known about the environmental impacts of mining, both on-site and off-site, and that body of information provides a basis for this chapter.
