ABSTRACT:
A process is described for continuously extracting a first liquid with a second liquid, the two liquids being capable of forming two separate phases defining a liquid-liquid interface. The process comprises contacting the two liquids in an apparatus defining a plurality of mixing chambers and at least one settling chamber, wherein the liquids are continuously agitated in the mixing chambers to provide mixing in a zone in the proximity of the liquid-liquid interface while maintaining substantial phase integrity beyond the agitation zone. Extracted liquids are separated in the settling chamber and removed from the apparatus.
