    摘要： The invention relates to a method for controlling and compressing a dispersion formed in the mixing stage of liquid-liquid extraction. The compression of the dispersion is achieved by reducing the cross-section of the separation section in the direction of flow and by equipping the separation section with a dispersion-damming member. The equipment according to the invention thus comprises a settler, which is essentially trapezoid in shape so that its cross-section is wider at the feed end of the settler and gets smaller towards the rear end of the settler, from whence the separated solutions are discharged from the settler, and the settler is equipped with at least one device to dam up the dispersion. In particular the method and equipment relate to the extraction process used in the recovery of metals.

    摘要： The invention relates to a method and apparatus with which the aqueous solution from liquid-liquid extraction in the hydrometallurgical recovery of metals is purified from droplets of organic extraction solution. The aqueous solution is treated in a settling tank, where it is made to flow through a flow channel area with a reduced cross-section that extends over the width of the tank at least at one point. The flow channels are located in the lower section of the droplet coalescer according to the invention, with the upper section of the device being mainly solid.
