ABSTRACT:
Solvent extraction of metallic mineral values from aqueous acidic solutions is improved by introducing a fine dispersion of air bubbles into the acid-extractant mixture to cause solid material normally occurring at the phase interface to float to the surface. This improved process is particularly applicable to the extraction of uranium from wet process phosphoric acid.
