Uranium Mill Tailings - Nuclear Regulatory …
Uranium Mill Tailings Uranium mill tailings are primarily the sandy process waste material from a conventional uranium mill.This ore residue contains the radioactive decay products from the uranium chains (mainly the U-238 chain) and heavy metals. As defined in Title 10, Part 40, of the Code of Federal Regulations (10 CFR Part 40), the tailings or wastes produced by the extraction or ...
Moab uranium mill tailings pile - Wikipedia
The Moab uranium mill tailings pile is a uranium mill waste pond situated alongside the Colorado River, currently under the control of the U.S. Department of Energy. Locals refer to it as the Moab Tailings Pile. In 1952 U.S. geologist Charles Steen found the largest uranium deposit in the United States near Moab, Utah. The uranium was processed by the Uranium Reduction Company and the waste slurry was stored in an unlined pond adjacent to the river. The Uranium Reduction Company was sold in 1962 and renam…
NRC: Backgrounder on Uranium Mill Tailings
Backgrounder on Uranium Mill Tailings Printable Version. On this page: Title I – Legacy sites; Title II - Sites licensed in 1978 or later; Milling is the first step in making natural uranium ore into fuel for nuclear reactors. Uranium mills use chemicals to extract uranium and make "yellowcake," a powder that can be processed into fuel.
Radioactive Waste From Uranium Mining and …
Mill tailings and raffinates are stored in specially designed ponds called impoundments. The tailings remain radioactive and contain hazardous chemicals from the recovery process. Image of a warning sign on forest access road near a uranium mining area in Mesa County, Colorado.
A multi-scalar study of the long-term reactivity of ...
The mill tailings from uranium mines constitute very low-level, long-lived, radioactive process waste. Their long-term management therefore requires a good understanding of the geochemical mechanisms regulating the mobility of residual uranium and radium-226.
Uranium Mill Tailings Remediation in the United …
Remediation of uranium mill tailings has techniques and procedures similar to all geoenvironmental clean-up programs, the only difference being the radioactive nature; although, heavy metals and leaching chemicals are of primary concern at some sites.

Uranium Tailings - Tox Town
31-5-2017 · Uranium tailings and uranium waste contain radium, which decays to produce radon, an invisible and odorless radioactive gas. Radon causes lung cancer, according to the National Toxicology Program. Uranium tailings and waste produce gamma radiation. Gamma rays are penetrating electromagnetic radiation that involves the decay of atomic nuclei.

This program facilitated the cleanup of 15 million cubic yards of uranium tailings at former uranium mill sites in nine western Colorado communities. Because much of the cleanup is complete, the focus has shifted to primarily "Post-UMTRA issues," or the discovery of new uranium mill tailings material by private citizens, utility companies or local governments.

Microbial Biogeochemistry of Uranium Mill Tailings ...
I. Introduction. Uranium mill tailings (UMT) are the crushed ore residues from the extraction of uranium (U) from ores. Except where ores have a high carbonate content, the commercial extraction of U from ores generally involves leaching with sulfuric acid (H 2 SO 4).The effluent (termed raffinate or barren solution) and tailings from the mill are discharged as slurry to a waste‐retention ...
