The invention relates to a method for guiding a dispersion of two liquids formed in the mixing stage of liquid-liquid extraction along the longitudinal axis of the separation section in the feed end of an extraction separation section. In particular the method and equipment relate to the extraction process used in the recovery of metals. In accordance with the method the dispersion to be fed into the separation section is guided so that it spreads evenly over the cross-section of the separation section using a directional member placed so as to obtain a vertical flow. The equipment in accordance with the invention consists of a directional member, which is in turn made up of at least two separate parts.
L'invention concerne un procédé permettant de guider une solution de dispersion de deux liquides formée durant l'étape de mélange d'une extraction liquide-liquide le long de l'axe longitudinal de la section de séparation dans l'extrémité d'alimentation d'une section de séparation par extraction. Plus spécifiquement, le procédé et l'équipement de cette invention concernent le processus d'extraction utilisé dans la récupération de métaux. Selon ce procédé, la solution de dispersion devant être amenée dans la section de séparation est guidée de façon à être répartie régulièrement sur la section transversale de la section de séparation à l'aide d'un élément de direction placé de façon à obtenir un écoulement vertical. L'équipement de cette invention consiste en un élément de direction qui consiste à son tour en au moins deux parties séparées.
