Abstract
A liquid-liquid counterflow extractor has a plurality of stacked stages each of which is provided with a mixer and a separator, the stages being traversed in succession by an upwardly flowing relatively low-density (light) phase and downwardly by the relatively high-density (heavy) phase. The separations of adjacent stages have lateral outlets which can be selectively connected to the inlets of a pump which can serve to displace one of the phases from one stage to another or to circulate a phase within one stage.
