enhancing the uranium recovery performance in gattar pilot plant using pulsed column technique

comparison of various technologies for uranium recovery from sulphuric acid leach solutions shows that the moving bed systems are more effective processing routes than fixed bed. developed system using air pulsation for resin moving was tested and examined for uranium recovery from gattar pilot plant project (north eastern desert, egypt) sulphuric acid leach liqour using chinese resin d263b.

recovery equilibrium and kinetic isotherms are established. the obtained results showed high performance and the validity of derived pulsed resin column for uranium extraction. elution behavior was improved by using intense fractional eluent which gives efficient results.
