The treatment of rare earths sulfate liquor contaminated with traces of uranium as radioactive contaminates utilizing lewatit mono plus M500 was studied. Adsorption behavior was studied by batch experiments to determine the optimum conditions for uranium removal. The obtained equilibrium data were found to be satisfactory fitted with Langmuir isotherm and the second order rate equation. Also, elution process was achieved by 2M NaCl/1M HCl solution and the reuse of sorbent remains appreciable. A marketable pure product of rare earth oxide was prepared in addition to pure sodium diuranate containing total uranium content of the starting REEs cake.
