Application of solvent-in-pulp technique for uranium extraction from mineralization granite

الملخص EN

Investigations on uranium extraction from a representative mineralized granite sample (Gattar granite GII) by solvent-in-pulp (SIP) technique were carried out in the present study.

For this purpose, the solvent (tri-butyl amine) (TBA) was mixed with the leaching slurry without prior filtration.

The influence of various factors affecting the SIP process, such as contact time, solvent concentration, dilution factor, type of surfactant, surfactant/solid ratio were studied.

About 91% uranium extraction efficiency was attained by the application of the chosen extraction SIP conditions.

Also, about 96% of the loaded uranium could be stripped by using sulfuric acid as an effective stripping agent.
