Uranium from phosphoric acid: Kinetic studies of the solvent extraction processes for uranium extraction

Desalination and Water Treatment, 2009
Kinetics of the mass transfer processes involved in uranium recovery from wet process phosphoric acid (WPA) by solvent extraction employing synergistic extractants has been studied. In the present investigation results on the kinetics of separation of entrained solvent by diluent washing and uranium mass transfer behaviour have been discussed.
