Uranium Mill Tailings Remediation in the United States

Uranium Mill Tailings Remediation in the United States

Nov 19, 2015 The use of radioactive material, specifically uranium, for the source of nuclear weapons and power spurred the movement toward exploration and mining of uranium ore in the United States. The uranium mill tailings, the waste by-product created during uranium extraction from the ore, posed concern because of the radioactive nature of the tailings

Is uranium ore dangerous? - Quora

Uranium ore is hazardous in significant quantities. Uranium itself isn’t particularly radioactive (unless enriched), but the ore will contain a significant amount of decay products which are significantly more radioactive. The ore will also releas

6 Potential Environmental Effects of Uranium Mining

6 Potential Environmental Effects of Uranium Mining

Although 90-95 percent of the uranium in the ore is extracted during processing (thus reducing uranium concentrations by at least an order of magnitude), most of the uranium decay products (e.g., 230 Th, 226 Ra, 222 Rn), which may comprise the majority of the total radioactivity of the ore, stay in the tailings (Hebel et al., 1978, Van Metre

Uranium Mining and Milling - Canadian Nuclear Safety

Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium. Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate
