Centrifugal extractors operate in a manner for performing liquid-liquid extractions, a feed solution containing one or more solutes and an immiscible solvent with a different density than that of the feed solution are fed to the mixing chamber located on the bottom of the centrifuge housing. A rotating agitator disc mixes the two immiscible liquids into dispersion. Different agitator disc designs can be used depending upon the liquids interfacial tension. The efficient mixing creates a large interfacial area between the two liquids to ensure maximum mass transfer of the solutes. The dispersion is aspirated into the centrifuge bowl by a turbine located on the bottom of the rotating bowl. The liquids are separated by the centrifugal force generated by the rotating bowl. The heavier liquid occupies the outer portion of the bowl and the light liquid occupies the inner portion of the bowl.
