Uranium U - PubChem

The remaining sand is called mill tailings. Tailings are rich in the chemicals and radioactive materials that were not removed, such as radium and thorium.One of the radioactive properties of uranium is half-life, or the time it takes for half of the isotope to give off its radiation and change into another substance. The half-lives are very long around 200,000 years for234U, 700 million years for235U, and 5 billion years

Uranium Reduction - Lawrence Berkeley National

2007-4-16  Uranium in the environment occurs primarily as 3 o f its 17 known isotopes, 238 U (99.27%), 235 U (0.72%), and 234 U (0.005%). All are ra-dioactive; however , it is the chemical toxi-city that is of greatest ecological risk (54). Being the forty-ninth most abundant ele-ment in the EarthÕ s crust, uranium is not rare. Unfortunately ,the anthropogenic use of

Waste Guide for the Uranium Milling Industry

WASTE SOLIDS Uranium ore enters the mill process as a solid, and for each ton of ore entering the mill 1 ton of solids, in either dis- solved or suspended form, must leave the mill. All of this solid material, except-that incorporated in the final uranium concen- trate product, leaves the mill as waste.
