ABSTRACT:
A method for the recovery of organic materials trapped in the emulsions generated in solvent extraction plants. The emulsions are first washed in aqueous solution. The washed emulsions are then subjected to a mechanical breaking process in aqueous/organic dispersion, inducing the inversion of the continuity of phases in the emulsions and the release of the phases involved. Subsequent separation of the phases by decanting enables the removal of significant quantities of solids and increases the overall recovery of the organic trapped in the emulsions.
