Abstract

The possibility of using Helianthus annuus extractant (sun flower) as a solvent extractant for uranium from its sulfate liquor as means for their recovery has been studied. Several experiments were conducted to determine the relevant factors affecting both the extraction and stripping of the uranium from a synthetic solution. Under the optimum conditions, the achieved uranium capacity has attained about 22 mg/g for the ethanolic extractant. The optimum stripping conditions for uranium content from the loaded ethanolic extractant which is rich of some active compound to form complex with uranium included stripping agent type 1M NaCl /1M HCl, aqueous to organic phase ratio (A/O) 1:3, stripping time 15 min and at room temp. From the prepared sulfate leach liquor of of Abu Zeneima ore material (South Eastern Sainai, Egypt) uranium has then been recovered using the working ethanolic extractant under the previously studied optimum conditions, with an efficiency of 98% The obtained strip liquor was then subjected to precipitation using NH4OH solution at pH of 7.5 and analysis of the obtained precipitate ammonium uranium oxide hydrate [UO3NH3H2O] was found assay 76% uranium which has been confirmed using XRD and EDAX analysis.
