Method and apparatus for controllably conducting a solution obtained from liquid-liquid extraction of two solutions and mixed into dispersion, to a wide settler

摘要

In a method according to the invention, a dispersion coming from a mixer part is conducted from downwards to the liquid part of the settler, into the middle part of the feed end, wherefrom it is set to be distributed to inside the settler part, in a closed channel-like space located in the immediate vicinity of the settler along the whole width of the settler and the flow therefrom mainly above the channel-like part towards the rear end of the settler. The method according to the invention is realized by means of an apparatus where an uptake shaft extending from the dispersion mixing tank to the settler opens into the feed end of the settler, from where there are further directed distribution channels towards the settler side edges. The distribution channels are placed in the bottom part of the settler.
