Abstract

A solvent extraction settler arrangement comprising a mixing unit for preparing a dispersion from mutually immiscible solutions and a settler having a feed end and a discharge end. The settler is arranged to separate solution phases from a dispersion fed from the feed end while the dispersion flows towards the discharge end. The arrangement further comprises a feeding device located at the feed end for feeding the dispersion prepared by the mixing unit to the settler. The feeding device comprises an elongated feed launder having a first end for receiving the dispersion from the mixing unit, and a second end. The feed launder extends alongside the feed end of the settler. The feed launder has a form of a conical tube with a cross-section converging towards the second end and an inclined bottom ascending towards the second end. A plurality of feed pipes are arranged along the length of the feed launder at a distance from each other, each feed pipe having a third end opening to the inner space of the feed launder at the bottom to receive the dispersion from the feed launder and a fourth end opening to the settler to conduct the dispersion to the settler.
