摘要：
The invention relates to a method for the controlled separation of a dispersion of two liquids formed in the mixing stage of liquid-liquid extraction into their own phases in the separation section of the extraction. In particular the method and equipment relate to the extraction process used in the recovery of metals. In accordance with the method the dispersion band remaining between the separated phases is dammed up using at least one revert member for said purpose located in the separation section. The equipment according to the invention comprises at least one revert member, which is in turn made up of at least two separate parts.
