The solvent extraction of U from carbonate solutions was studied. The prevention of silica staabilized emulsions in the Amex and Dapex processes by solventcontinuous mixing is reported. The recovery of U and Pu from H/sub 2/SO/ sub 4/ decladding solutions by continuous countercurrent extraction with primary amines, HNO/sub 3/ stripping from primary amine, U/sup 6+/ extraction by primary amine, and U extraction by dialkylphosphoric acid is being studied. Plutonium was effectively freed from Am contamination by extraction from 2 M HNO/sub 3/ with 0.1 M di(2-ethylhexyl)phosphoric acid. ( For preceding period see CF-59-7- 68), (W.L.H.
