Separation and Purification of Cerium from Egyptian Monazite Sands

AbstractA process is described for the recovery of cerium from crude cerium(III) nitrate solution as sodium cerium sulphate. The double sulphate is then treated with 18% NaOH solution and dried at 110°C to hydrated ceric oxide.The purification of crude cerium by solvent extraction was studied and data are presented on the effect of several variables on the distribution coefficient of Ce(IV) between nitric acid and tributyl phosphate‐kerosene. After extraction and scrubbing the cerium compounds obtained were found to be of spectroscopic purity grade.
