The book reviews the principles of ion exchange and the use of ion exchange resins in uranium recovery. Part I discusses the fundamentals of ion exchange, the structure, propertries and the main processes using ion exchange resins. Part 2 covers the recovery of uranium from acidic or alkaline leach liquors. In this section, the chemistry involved, the main factors affecting the resins performance, the equipment in which the resins are used, the main problems encountered and how one can evaluate resins in the laboratory are discussed. The focus is on ion exchange rather than on uranium hydrometallurgy and therefore this book is addressed to all those involved in the uranium industry for which ion exchange chemistry and techlogy is t their major field of expertise.
