Abstract
This paper describes a simple method for cerium separation and purification. Cerium is previously precipitated with N H{sub 3}/air/H{sub 2} O{sub 2} system in a mixed chlorides solution obtained from Brazilian monazite treatment. The cerium fraction as cerium chloride is run down throughout a strong cationic resin bed and then the rare earth impurities separation is done by elution of the resin with separation ammonium salt of EDTA. None retainer ion is used in the purification technique by ion exchange. (author).
