Abstract

See full text

The method and apparatus according to the invention relate to conducting the dispersion of two phases, created in the mixing unit (1) of liquid--liquid extraction, from the mixing unit to the separation part (2), in which case the flow direction of the dispersion discharged from the mixing unit asymmetrically with respect to the separation part is turned to be symmetrical with respect to the separation part. In the last mixer (4) of the mixing unit, the orientation of the dispersion is turned to be parallel to the lengthwise axis of the separation part, by means of flow-turning members (9), the dispersion flow is discharged from the mixing unit at the height of the mixer bottom (10) and conducted to an uptake shaft (11) parallel to the lengthwise axis of the separation part, where the dispersion flow is turned upwards and made to be discharged symmetrically into the separation part.
