SOLVENT EXTRACTION OF URANIUM FROM CARBONATE
Abstract. A process for recovering uranium from carbonate leach liquors by extraction with quaternary ammonium compounds was developed and evaluated in bench-scale continuous equipment with synthetic liquors. Uranium was recovered from the solvent by direct precipitation with sodium hydroxide --sodium carbonate solution.Uranium Processing Presentation | Uranium | Enriched,2015. 3. 1.· Uranium processing Presentation - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online.
