摘要： The invention relates to a method and arrangement for separating two solutions mixed in dispersion into two solution phases in a liquid-liquid extraction separation cell. The arrangement includes a first guide wall extending along the whole width of the cell with respect to the vertical direction at an inclined angle. The first guide wall includes a bottom edge, which is located at a distance from the cell bottom, so that a clearance gap is formed between the bottom edge and the cell bottom. The arrangement also includes a second guide wall essentially parallel with the first guide wall and placed at a distance therefrom. Between the first guide wall and the second guide wall an uptake shaft is formed extending diagonally upwards at the inclined angle. The second guide wall is pressed tightly against the cell bottom, and includes a number of vertical slots.
