ABSTRACT:
A solvent extraction process is provided for transferring metal values from one immiscible liquid phase to another, whereby the two liquid phases are vigorously mixed together in a first mixer under conditions in which one liquid phase is rendered continuous, the mixing being continued to effect complete transfer of metal values, and the mixture then passed to a second mixer and the two phases mixed under conditions in which the other phase is rendered continuous, whereby when the two phases are fed to a settler, the rate of disengagement of the two immiscible liquids is substantially increased.
