ABSTRACT:
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.
