Comparative study for leaching processes of uranium, copper and cadmium from gibbsite ore material of Talet Seleim, Southwestern, Sinai, Egypt

In this paper, leaching characteristics are presented, and a cost-effective process for extracting uranium, copper, and cadmium from Talet Seleim’s Gibbsite is developed. H 2 SO 4 was chosen as the preferable leaching agent based on the agitation experiment’s findings. The leaching efficiencies of U, Cu, and Cd attained 95%, 90%, and 89%, respectively, under the investigated ideal circumstances. Kinetic study of leaching process proved diffusion controlling mechanisms with activation energies: 29.59, 29.30, and 34.84 kJ/mol, respectively. U was recovered using Amberlite IRA 400, while Cu and Cd were precipitated from Talet Seleim’s gibbsite’s sulphate leachate. Finally, the tentative treatment procedure's preliminary flowsheet was then given.
