Extraction of Rare-Earth Elements with Solutions of tri-n-Butyl Phosphate under Local Vibrational Impact in Static and Flow-through Systems

Abstract

Results are presented of a study of the influence exerted by a local vibrational impact in the dynamic interfacial layer on the extraction of rare-earth elements with tri-n-butyl phosphate solutions in a diluent in static and flow-through systems. It is shown that, in the case of local vibrations in the dynamic interfacial layer, the extraction acceleration factor is determined by the nature of a diluent, vibration frequency of the vibrating element, and fluid motion rate and is nearly independent of the nature of an element being extracted.
