      This book is the collection of papers from the latest International Uranium Mining and Hydrogeology Conference (UMH VII) held in September , in Freiberg, Germany. It is divided to five sessions: Uranium Mining, Uranium and Phosphates, Clean-up technologies for water and soil. Uranium and Developing a 3D data model for geohazard assessment in a former uraniferous mining site.- Uranium and heavy metals in Phosphate Fertilizers.- Uranium accumulation in sandy soil in an arid region due to agricultural activities.- Uranium in anthropogenic Lakes of the New Central German Lake District.- Closure of Underground Mine of Lincang

        Between the s and the s, millions of tons of uranium ore were mined from square-mile reservation that spans Arizona, New Mexico and Utah. Many Navajos, unaware of the dangers of contamination, built their homes with chunks of uranium ore and mill :// Radium-bearing barytes (radiobarytes) have been known since the beginning of the 20th century. They are mainly found as precipitates of low-temperature hydrothermal solutions. In anthropogenic environments, they frequently occur as crusts on oil industry equipment used for borehole extraction, in leachates from uranium mill tailings, and as a by-product of phosphoric acid ://

      Radioactive Waste Streams: An Overview of Waste Classification for Disposal Summary Radioactive waste is a byproduct of nuclear weapons production, commercial nuclear power generation, and the naval reactor program. Waste byproducts also result from radioisotopes used for scientific, medical, and industrial purposes. The legislative definitions adopted for radioactive wastes, for the most part This chapter highlights the key steps in the nuclear fuel cycle where biological treatment strategies may replace or augment existing chemical processes. Radionuclide-containing wastes are produced at all steps in the nuclear fuel cycle. The mechanisms of microbial interactions with key radionuclides in the wastes are discussed alongside the possible antagonistic effects of other organic and

[H R Beard; H B Salisbury; M B Shirts] Tailing and soil samples from New Mexico were evaluated for their potential to absorb radium and thorium from tailing liquors. Absorption ranged from 0 to 97 pct for radium and 0 to 60 pct for thorium. Some samples that readily absorbed radium were contacted with various salt solutions that could be present in tailing solutions to determine @article{osti_, title = {Absorption of radium and thorium from Wyoming and Utah uranium mill tailings solutions}, author = {Beard, H R and Nichols, I L and Seidel, D C}, abstractNote = {An investigation was made of the absorption of radium and thorium from waste uranium leach liquor by clays and other materials.

Based on the current understanding of uranium deposits in the Commonwealth of Virginia, extraction of uranium ore would use open-pit mining, or underground mining, or a combination of both ().These general terms incorporate a large variety of design possibilities—there are as many methods of mining uranium as there are orebody sizes, shapes, and mineral :// The results show that overall a sample mass of g with addition of 20 mL concentrated nitric acid is the most efficient means for extracting uranium and thorium simultaneously from apatite The legacy of radium and uranium mines in Europe is used to illustrate old mining practices, their environmental and social impacts, and remediation costs.

New mining projects are expected today to incorporate lessons from past mining activities and meet societal and development needs in a more efficient and less damaging way to the :// Uranium (/ j ʊ ˈ r eɪ n i ə m / yew-RAY-nee-əm) is a silvery-white metallic chemical element in the actinide series of the periodic table, with atomic number It is assigned the chemical symbol U.A uranium atom has 92 protons and 92 electrons, of which 6 are valence uranium nucleus binds between and neutrons, establishing six isotopes ( U through U), the Cover Photo Aerial photograph of Shiprock, New Mexico uranium mill tailings pile and surrounding area, The view is looking toward the south and shows the San Juan River in the foreground, the covered Shiprock tailings pile in the left center and the Navajo community of Shiprock in The solubility of thorium increases in acidic aqueous solutions, and so tailings solutions can contain very high concentrations of Th under acid-generating conditions.
