Clelland, D W; Cullen, E J

A method of recovering uranium from magnesium fluoride or calcium fluoride slags is described. These slags arise in the production of uranium from uranium tetrafluoride. The method consists of grinding the slag dry and then slurrying with nitric acid. The resultant slurry is fed to a packed, pulsed counter-current extraction column having an unpacked disengagement section at its base. An organic solvent for uranium flows upward and the slurry flows downward in the column. The interface between the two phases is within the disengagement section, and the packing and pulsing is arranged so that the discontinuous phase flows over the packing and through the continuous phase as a film. The packing consists of glass spheres supported in the column on a conlcal sieve plate. A diagram is given of the process and the equipment used. (N.W.R.)
