Abstract: For extracting of rare earth elements (REE) from the industrial wastes,adsorption process is applied. Natural clinoptilolite was thermally treated andused as an adsorbent for the removal of REE from byproducts residue ofphosphoric acid industry (Sample-I) as well as Abu-Rusheid Project (Sample-II)in Egyptian Nuclear Materials Authority. The factors affected the adsorptionprocess were studied such as; effect of time, temperature, agitation speed, andmass/volume (m/v), in addition to sequential chemical treatment during differentsteps. The results showed that by using thermal clinoptilolite 87% and 91% ofREE were removed from the treated solutions of Sample-I, and Sample-IIrespectively. The stripping of REE from clinoptilolite was carried out using(0.5M) Na2CO3 for 30 minutes at room temperature, the stripping percent of rareearth elements was achieved 95.8 % and 87.6 % for clinoptilolite bearing SampleI & that bearing Sample-II respectively.
