Abstract
ABSTRACTA new trend for the recovery of uranium from hydrous oxide cake produced after alkali breakdown of Rosetta monazite mineral concentrate via Di-ethylene Tri-amine Penta Acetic acid (DTPA) lixiviate was applied. The procedure based on the selective chelating behavior of Di-ethylene Tri-amine Penta Acetic acid (DTPA) towards both Th(IV) (98%) and REEs (99%) leaving uranium alone”. Both the reaction mechanism and kinetic studies of the dissolution process have been interpreted. The results show that the dissolution mechanism of thorium and REEs were chemically controlled and the recorded activation energy was 30.03 and 35.258 kJ/mol for Th(IV) and REEs respectively.
