A multistage liquid-liquid extraction apparatus of the mixer-settler type, which is especially suited for performing liquid-liquid extractions accompanied by the formation of a solid phase, comprises a vessel the side-wall of which defines a cylinder or a regular polygonal body, the vessel being divided by means of radial partitions into sectors, each sector comprising a mixer and a settler, and the mixers and the settlers being located near the side-wall of the vessel. The agitators of the mixers are constituted by pumping turbines; the outlets of the mixers are constituted by weirs located near the side-wall of the vessel; means are provided for making the mixed liquids, discharged at the outlet of the mixers, flow by gravity towards a zone near the axis of the vessel; and the bottom of the vessel is inclined towards the axis of the vessel so as to define a reversed cone or pyramid. |
