Available in PDF, EPUB and Kindle. Book excerpt: Reduction of small charges of uranium tetrafluoride with magnesium proved to be successful. By hand-tamping of UF4- Mg blend, tap densities ranging between3.1 and 3.4 g/cc were obtained. The reduction yields for these densities ranged from 72.79 to 93.71%. In the case of machine-compacted UF4-Mg blend having tap densities from 3.58 to 3.68 g/cc, reduction yields were higher, ranging between 91.45 and 97.2%. Machine-compacted blends gave much more uniform temperature distribution curves during the preheating period, as a result of higher tap densities. The best yields were obtained by firing a machine- compacted blend containing 5% Mg excess at a furnace temperature of 650 deg C, giving an average crude metal yield of 96.3%. However, the high carbon content of 174 ppm in the crude uranium biscuits obtained by compacts reduction, as a result of hydrocarbon binder presence, appeared to be a disadvantage. Attempts were also made to demonstrate the initiation of the reduction reaction at temperatures lower than 500 deg C by taking x-ray-diffraction patterns of the samples of the UF4-Mg charges heated up to various temperatures.

Book excerpt: Due to difficulties encountered in the production of calcium metal in adequate quantity and of adequate purity at low cost, it became desirable to replace calcium by a cheaper metal in the production of uranium. Because of the heats of formation of its compounds, its relative stability in air, and its cheapness in high purities, magnesium was the best suited metal for the purpose. Since the heat of reaction of the reduction of UF4 by Mg was not sufficient to melt the products, it was necessary to add heat to the system. This was done in experimental studies both by preheating the reactants before reaction was initiated and by the use of a simultaneous auxiliary reaction producing more heat than the primary reaction. For the latter purpose the reductions of KClO3, K2S2O8 and of other salts by Mg were suitable reactions. The use of 'boosters' or auxiliary oxidants involved extra work and materials, thus increasing costs and offering additional opportunity for contamination, hence the preheating of the reactants was adopted for large scale production.

Available in PDF, EPUB and Kindle. Book excerpt: The book emphasizes various aspects of processing secondary sources for recovery of uranium. The field of secondary resource processing is gaining ground over the last few years as it is eco-friendly, economical and in tune with the philosophy of sustainable development. The book is the first one of its type in the area and includes a succint and comprehensive description of related areas of ore mineralogy, resource classification, processing principles involved in uranium solubilisation followed by separation and safety aspects. The clear organisation and the carefully selected figures and tables makes the treatment invaluable for practising engineers, research workers and academic institutions.
