Abstract

See full text

A solvent extraction method for hydrometallurgical liquid-liquid extraction processes, in which method solution phases are separated from a dispersion while the dispersion flows horizontally in a settler from a feed end to a discharge end. The mass flow of the dispersion and solution phases is divided into a plurality of parallel and mutually separated plug flows flowing in the settler from the feed end to the discharge end. The settler (1) comprises a plurality of elongated settler sections (4) which are mutually separated and side by side in parallel to each other, Inc settler sections (4) extending from the feed end (2) to the discharge end (3), forming a plurality of mutually separated parallel plug flow channels.
