A Closer Look at Uranium Tailings Canadian Nuclear

The conventional process for uranium production starts with the extraction of uranium ore from a mine. After that, the uranium ore is physically and chemically processed in a mill where it is ground into a fine sand, allowing the uranium to be leached out and recovered. The remaining waste solids, known as “tailings”, are a complex mixture of minerals and precipitates, containing naturally

Uranium Mill Tailings Remediation Performed by the US DOE

UMTRCA established clean up requirements for all US uranium mill tailings sites. The Act passed Congress in 1978 following disclosure of the use of tailings in homes and schools and other tailings-related pollution problems at a time when a uranium production “boom” to feed a new generation of nuclear power stations was projected. The Act’s purpose, as drafted by the US Congress is
