Book Description
This report summarizes the work done at MIT during FY 1981 on the overall system design of a uranium-from-seawater facility. It consists of a sequence of seven major chapters, each of which was originally prepared as a stand-alone internal progress report. These chapters trace the historical progression of the MIT effort, from an early concern with scoping calculations to define the practical boundaries of a design envelope, as constrained by elementary economic and energy balance considerations, through a parallel evaluation of actively-pumped and passive current-driven concepts, and thence to quantification of the features of a second generation system based on a shipboard-mounted, actively-pumped concept designed around the use of thin beds of powdered ion exchange resin supported by cloth fiber cylinders (similar to the baghouse flyash filters used on power station offgas). An assessment of the apparently inherent limitations of even thin settled-bed sorber media then led to selection of an expanded bed (in the form of an ion exchange "wool"), which would permit an order of magnitude increase in flow loading, as a desirable advance. Thus the final two chapters evaluate ways in which this approach could be implemented, and the resulting performance levels which could be attained. Overall, U 308 production costs under 200 $/lb appear to be within reach if a high capacity (several thousand ppm U) ion exchange wool can be developed.

Book Description
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 technology is not their major field of expertise.
