Title:
IMPROVED LIQUID MEMBRANE PROCESS FOR URANIUM RECOVERY
Document Type and Number:
Japanese Patent JPS589823
Kind Code:
A
Abstract:
An emulsion extraction process for recovering uranium from a WPPA feed solution containing uranyl cations wherein the WPPA feed is contacted with a water-in-oil emulsion which extracts and captures the uranium in the emulsion, wherein the improvement comprises adding excess oxidizing agent to the WPPA feed before or during the time that the feed is contacted with the emulsion. This results in both higher levels of uranium extraction and higher concentrations of uranium in the emulsion.
