Abstract
A method and arrangement for separating two solutions mixed in dispersion into two solution phases in a liquid-liquid extraction separation cell. A lighter solution phase placed on the heavier solution phase is forced to flow as a thin overflow layer over the top edge of a front panel such that the dispersion thickens A rear panel is essentially parallel with the front panel so that in between the front panel and the rear panel, there is formed an uptake shaft along which the thickened dispersion can rise and be compressed.
