ABSTRACT OF THE DISCLOSURE An extraction unit of the type having successively in the flow direction of the liquid, a mixer, a pre-settler and a settler, the pre- settler and the settler being separated from each other by several successive perforated partition walls, the perforations of each partition wall being laterally unaligned with the perforations of the following partition wall, the lower section of the mixer having inlets for the heavy phase and the light phase and a mechanical stirrer for mixing the heavy phase and the light phase to form a dispersion, and the upper section having at least one opening for directing the dispersion from the mixer to the pre-settler, the upper section of the settler having members for removing the separated light phase as an overflow from the settler, the lower section of which has an opening for the removal of the separated heavy phase from the settler as a controlled flow, and between the settler and the mixer there are pipes for returning part of the separated heavy and light phase from the settler to the lower section of the mixer. The mixer is at least in part surrounded by the pre- settler and the openings for directing the dispersion from the mixer into the pre-settler are on those sides of the mixer which are facing away from the perforated partition walls between the pre-settler and the settler, in order to lengthen the path of the dispersion coming from the mixer and to divide it into two partial flows following each side of the mixer and to cause these flows to impinge against each other before reaching the said perforated partition walls, in order to damp the flow and to promote the separation of the phase.
