No relevant papers were found, but approximately publications were identified in a less specific search for methods of removing uranium from water. Most of the latter publications dealt with the recovery of uranium from ores, industrial and analytical chemistry solutions, or sea- water. The recovery of uranium (U) from seawater has been investigated for over six decades in efforts to secure uranium sources for future energy production. The majority of the research activities have focused on inorganic materials, chelating polymers, and by:

Uranium and daughter nuclides and basic research and modeling. operation and Development (OECD/NEA) and the IAEA jointly published a book on Uranium Extraction Technology. A primary objective of this report was Uranium recovery from low-level aqueous sources book docu ment the significant technological developments that took place during the s.
The purpose of this present publication is to update and expand the original book. After accumulating uranium at low level in the wastewater, the flocs were eluted. The eluate was then digested in acid and followed by alkaline precipitation to obtain the uranium-containing product.
The mol/L HNO 3 solution (volume ratio of acid:eluate = ) decomposed the organic ALR to CO 2 and H 2 O in a continuously boiling aqueous solution.

have jointly prepared periodic updates (currently every two years) on world uranium resources, production and demand. Such updates have been published in what are commonly known as the “Red Books”. The 26th edition of the Red Book reflects information current as of 1 January File Size: 8MB.
There, the yellowcake is transformed into fuel for nuclear power reactors. In addition to yellowcake, uranium recovery operations generate waste products, called byproduct materials, that contain low levels of radioactivity.
For mining activities, the regulatory responsibility depends on the extraction method that the given facility uses. Specifically, conventional mining (where uranium ore is removed.
As mentioned above, after shortly reaching a peak in the 13th days of the field trial, the uranium concentration kept at a low level until the ferric solution was injected.

The Red Book tabulates abouttU in Sweden and menti tU in Finland at the Sotkamo mine of Terrafame Oy, for which the government granted a permit in for uranium recovery by heap leaching.
Thorium as a nuclear fuel. Today uranium is the only fuel supplied for nuclear reactors. the uranium concentration in acid leach solution is high, for example, > mg/L U, SX is more preferable than IX in term of costs (Tonder and KotzeIvanova et al.
Additionally, solvent extraction is also widely used and investigated for uranium recovery as a by-product from processes for. The book presents the results from the Uranium Mining and Hydrogeology Conference (UMH VI) held in Septemberin 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. The World Distribution of Uranium Deposits database tabulates 14 million tonnes, though the Red Book tabulates only about 8 million tonnes.
With uranium as a minor by-product of phosphates, the potential supply is tied to the economics of phosphate production, as well as uranium price, coupled with the environmental benefits of removing uranium from the waste stream and/or product. Given the vast quantity of uranium naturally found in the ocean, adsorbent materials have been investigated to recover this vital fuel source.
Amidoxime (AO) has been found to be the state-of-the-art functional group for this purpose, however, improvements must still be made to overcome the issues with selectively capturing uranium at such a low concentration found in the by: 6.

Finding solutions is of interest not only for nuclear waste management for power plants, hospitals, research facilities, and in case of a nuclear disaster, but also for capturing unconventional sources of uranium.

Uranium for Nuclear Power: Resources, Mining and Transformation to Fuel discusses the nuclear industry and its dependence on a steady supply of competitively priced uranium as a key factor in its long-term sustainability.
A better understanding of uranium ore geology and advances in exploration and mining methods will facilitate the discovery and exploitation of new uranium deposits.
in uranium resources, production, demand and the environment.” Accordingly, the papers presented at this meeting are about evenly divided between discussions of known and potential uranium resources and uranium production technology and the environmental impact of uranium mining and processing, its related remediation technology and its costs.The aqueous sources of soluble uranium were surveyed and evaluated in terms of the uranium geochemical cycle in an effort to identify potential unexploited resources.
Freshwater sources appeared to be too low in uranium content to merit consideration, while seawater, although very dilute (approx. ppB), contains approx. 4 x 10/sup 9/ metric tons of uranium in all the world's oceans.We developed a simple, safe method to remove uranium from contaminated metallic surfaces so that the materials can be recycled or disposed of as low-level radioactive or nonradioactive waste.
