A solvent extraction process is described for separating Th, U, and rare earths from monazite sands. Thorium purification involves coextraction of cerium and thorium; the cerium value is recovered concurrent with thorium. The anion exchange techniques for recovery of U are advantageous to solvent extraction methods, as anion exchange inherently avoids cation contamination and gives generally higher recovery. The over-all significance of the process is that thorium, uranium, and rare earths are recovered in both high yield and purity. (W.L.H.)
