ABSTRACT

 

This article studies the effect of ion exchange method and the amount of rare earth element absorption by Dowex 5owx8 (H+) resin in Acid- Leaching solution of Saghand’S uranium mine in Iran. In this research, column method has been used for separating yttrium, cerium and lanthanum, because ion exchange process is one of the effective processes in separation and extraction of rare earth elements. After region sampling and doing XRF and ICP-MS analyzer process on the sample, the obtained solution from the region’S acid leaching including 500ppm yttrium, 580ppm cerium and 940ppm lanthanum, has been contacted by different amounts of Dowex 5owx8 (H+)) resin (100-200 mesh). In each experiment, 50cc of the sample has been contacted with different amounts of (0.25
