Abstract
Multi-phase mixtures are resolved into separate phases by introducing the mixture into a body of liquid which contains a solvent for one of said phases and has a specific gravity intermediate two insoluble phases of the mixture. The latter accordingly migrate to different levels in the body of liquid and can be separately recovered therefrom. Solvent laden with the soluble phase is also separately removed from the body of liquid, and the solvent can then be stripped to isolate the soluble phase.
