ADSORPTION METHOD FOR SEPARATING THORIUM VALUES FROM URANIUM VALUES

Patent Boyd, G E; Russell, E R; Schubert, J

An improved ion exchange method is described for recovery of uranium and thorium values as separate functions from an aqueous acidic solution containing less than 10/sup -3/ M thorium ions and between 0.1 and 1 M uranyl ions. The solution is passed through a bed of cation exchange resin in the acid form to adsorb all the thorium ions and a portion of the uranyl ions. The uranium is eluted by means of aqueous 0.1 to 0.4 M sulfuric acid. The thorium may then be stripped from the resin by elution with aqueous 0.5 M oxalic acid.
METHOD FOR SEPARATING THORIUM AND YTTRIUM VALUES

Patent Vanderkooi, W N

A method is presented for the recovery of thorium and yttrium values from dilute aqueous acidic solutions. The aqueous acidic salt solution containing dissolved thorium and yttrium values is brought into contact with a bed of a chelating resin, which shows a preferential sorption for the thorium values. The chelating resin can be easily regenerated for reuse. (R.J.S.)

Method for dissolving hard-to-dissolve thorium and/or plutonium oxides

Patent Ledebrink, F -W; Rosenkranz, W; Stoll, W

Method for dissolving hard-to-dissolve thorium and/or plutonium oxides, especially dioxides such as ThO2, PuO2 or (U/Pu)O2 mixed oxides by heating the oxides in a hermetically sealed vessel in fluoride-free nitric acid. The use of a gas atmosphere containing oxygen in the sealed vessel is advantageous.
METHOD FOR DISSOLVING LANTHANUM FLUORIDE CARRIER FOR PLUTONIUM

Patent Koshland, Jr, D E; Willard, J E

A method is described for dissolving lanthanum fluoride precipitates which is applicable to lanthanum fluoride carrier precipitation processes for recovery of plutonium values from aqueous solutions. The lanthanum fluoride precipitate is contacted with an aqueous acidic solution containing dissolved zirconium in the tetravalent oxidation state. The presence of the zirconium increases the lanthanum fluoride dissolved and makes any tetravalent plutonium present more readily oxidizable to the hexavalent state. (AEC)
