摘要：A process and apparatus are described for stripping uranium values from auranium-loaded organic extractant phase containing, usually, a tertiary amine capable offorming organic-soluble uranium complexes. The sulphate-containing aqueous stripliquor is fed in co-current with the extractant phase to be stripped through a number ofmixing stages in series connected one to another without intermediate settling stagesand finally to a final settling stage. A \"primary\" dispersion is maintained in each mixingstage and controlled stepwise pH adjustment of the mixing stages is effected bymetered addition of a base, such as ammonia.
