Uranium, solvent exchange data

Babcock ( ) also reported pilot plant uranium and chromium recovery projects using ILMs. Membrane modules were constructed with hollow fiber polysulfone supports containing kerosene solutions of commercially available hydrometallurgical complexatlon agents such as tertiary amines. Operating coats for the extraction step calculated from uranium recovery data were 0.8/kg Ur for a 3.8 x 10 ra /day plant which were superior to costs associated with solvent extraction and ion-exchange. 

Pilot plant uranium and chromium recovery data for a SLM system was reported by Babcock (65). Polysulfone hollow fibers were used in the module and a tertiary amine in kerosene was the organic phase. Operational costs for the separation of uranium were 0.8/Kg for a 3.8 X 10 m /day plant. This cost estimate was lower than those for uranium recovery by solvent extraction and ion exchange.
