Get PriceSep 21, 2018·Uranium miningrisks. Risks common touranium miningare centred on radiation. Countries such as Australia and Canada have really clamped down onuraniummining and how they deal with the radioactive impact of the material. Everyone is exposed to radiation, so the new rules and regulations arounduraniummining are based on keeping overexposure under the specified limits.
Mining:Whenuraniumis near the surface,minersdig the rock out of open pits. Open pitminingstrips away the topsoil and rock that lie above theuranium ore.Whenuraniumis found deep underground,minersmust dig undergroundminesto reach it. The rock is then removed through underground tunnels.

Uranium minerals are always associated with more radioactive elements such as radium and radon in the ore which arise from the radioactive decay of uranium over a few million of years. Therefore, although uranium itself is barely radioactive, the ore which is mined, especially if it is very high-grade such as in some Canadian mines, is handled with some care, for occupational health and safety reasons.
Experts and miners will use machines and explosives to create a pit. Then, they'll remove the uranium ore in chunks to be transported for further processing. Miners are specially trained to separate ore from waste. Often, they keep this motto in mind: "A mine is a terrible thing to waste, and waste is a terrible thing to mine" [source: Hunter]. Open-pit differs from other types of surface mining, which remove …
Jun 01, 2016· Phosphate ores typically contain about 1500 Bq/kg of uranium and radium, although some phosphates contain up to 20,000 Bq/kg of U3O8(Paschoa and Godoy, 2002). In general, phosphate ores of sedimentary origin have higher concentrations of radionuclides of the uranium family. In 90% of cases, the ore is treated with sulfuric acid.
In 1976 a mineral deposit of uranium was discovered in the municipality of Santa Quitéria, State of Ceará. In 2006, the federal government shows interest in exploring the deposit. By this year (2016), the aim of the Brazilian Nuclear Industries (INB) was to extract uranium and phosphate (for the agroindustry).
