Abstract
An object of the present invention is to provide a separation method capable of efficiently separating a light liquid and a heavy liquid from a mixed liquid containing the light liquid, the heavy liquid, and an emulsion liquid of the light liquid and the heavy liquid, such as an emulsion-layer extraction liquid in a vicinity of an interface in an extraction column. The present invention relates to a separation method for continuously separating a light liquid and a heavy liquid having a specific gravity larger than that of the light liquid from a mixed liquid containing the light liquid, the heavy liquid, and an emulsion liquid of the light liquid and the heavy liquid by introducing the mixed liquid into a separation tank, in which a specific separation layer is used for the separation tank.
