ABSTRACT:
A process for treatment of a liquid stream, optionally comprising solids such as minerals, comprises passing at least two different treating reagents through contactors each comprising a drum with a rotor having axially spaced discs compartmentalizing the drum interior and carrying receptacles which rotate with the rotor and cause transfer of portions of one phase in the contactor to the other phase as the rotor turns. The liquid stream being treated is caused to flow along a path including, in succession, parts of each contactor so that the liquid stream is brought into contact with the reagents successively and in rotation.
