Uranium Mining And Management

This book examines uranium mining and management in the United States with a focus on federal considerations. From 2005 to 2007, uranium prices increased from about $20 a pound to over $140 a pound, which led to renewed interest in uranium mining, both exploration and extraction, on federal land in the U.S. In early 2012, thousands of claims have been filed to explore for and potentially extract uranium on federal land. This increase in claims filed, has raised concerns about the potential impacts that an increased level of uranium exploration and extraction could have on the environment. During uranium extraction, the waste rock piles that are formed can introduce radionuclides (such as radium) and heavy metals (such as selenium and arsenic) into the environment. Before the mid-1970s, many mines on federal land, were abandoned without any reclamation, leaving a costly legacy of abandoned mines that pose potential health, safety, and environmental hazards.

This publication has been written to assist member states in the development of their uranium mineral resources. It sets out the basic tenets of best practice in terms of environmental management of uranium mining and processing operations from the viewpoint of both operators and regulators, and is accompanied by a collection of case studies from leading representatives in the global mining industry. Includes CD-ROM with papers presented at an IAEA technical meeting in Saskatoon, Canada, June 22-25, 2005.--Publisher's description.

Discusses effectiveness of uranium mine radiation safety standards, and Federal Radiation Council efforts to establish official radiation exposure safety standards for uranium miners. Includes Resource Management Corp. report UR-042 "Control of Radiation Exposure in Uranium Mines: A Cost and Economic Analysis," Nov. 4, 1968 (p. 223-299).

Uranium is an element to be found ubiquitous in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds μg/l without impact from mining, nuclear industry, and fertilizers. Considering the WHO recommendation for drinking water of 15 μg/l (has been as low as 2 μg/l before) due to the chemical toxicity of uranium the element uranium has become an important issue in environmental research. Besides natural enrichment of uranium in aquifers uranium mining and milling activities, further uranium processing to nuclear fuel, emissions form burning coal and oil, and the application of uranium containing phosphate fertilizers may enrich the natural uranium concentrations in soil and water by far. In October 1995 the first international conference on Uranium Mining and Hydrogeology (UMH I) was held in Freiberg being organized by the Department of Geology at the Technical University Bergakademie Freiberg by the support of the Saxon State Ministry of Geology and Environment. Due to the large scientific interest in the topic of uranium a second conference (UMH II) took place in Freiberg in September 1998. Furthermore, in September 2002 scientists working on the topic of uranium mining and hydrogeology attended the third conference (UMH III) which was jointly held together with the International Mine Water - sociation (IMWA) Symposium 2002. The reviewed papers and posters of the 2002 conference have been published by Springer entitled Uranium in the aquatic en- ronment (edited by Merkel, Planer-Friedrich and Wolkersdorfer).

The book presents the results from the Uranium Mining and Hydrogeology Conference (UMH VI) held in September 2011, in Freiberg, Germany. The following subjects are emphasised: Uranium Mining, Phosphate Mining and Uranium recovery. Cleaning up technologies for water and soil. Analysis and sensor for Uranium and Radon and Modelling.
