Abstract
In the process of uranium recovery from wet-process phosphoric acid, post treatment of the raffinate phosphoric acid is very important to prevent damage to the rubber linings of the acid evaporators and to recover the solvent for reuse. A simple and continuous method using an inclined parallel-corrugated-plate separator to remove the organic solvent entrainment from the raffinate phosphoric acid is established herein.
