Pertraction of neodymium by a dedicated solvent

Abstract : The process called pertraction or non-dispersive solvent extraction (NDSX) is a technique which allows the metals recovery from leach solutions. It is a liquid-liquid extractor in which the interfacial area is delimited by a porous membrane separating two immiscible phases, the aqueous phase containing the species to be extracted and the organic phase forming the extractant. In the case of the figure bellow, organic phase passing through the shell side of the module wets the hydrophobic membrane. A non-wetting aqueous phase is passed through the lumen side of the membrane.
