Thorium is removed from raffinate effluent by pre-washing with odourless kerosene to remove organic contaminants, followed by solvent extraction counter-currently with tri-n-octylphosphine oxide in odourless kerosene. The loaded solvent from the solvent extraction is back-washed with K2CO3 solution at about 60°C, and subsequent lime addition precipitates Th(OH)4.

Le thorium est éliminé dans l'effluent d'un raffinat par pré-lavage avec du kérosène inodore pour séparer les contaminants organiques, suivi d'une extraction à contre-courant à l'aide d'un solvant à l'oxyde de tri-n-octylphosphine dans du kérosène inodore. Après extraction, le solvant chargé est lavé par retour d'une solution de K2CO3 à 60 degrés C environ; l'addition ultérieure de chaux précipite le Th(OH)4.
