Recovery of uranium, thorium and zirconium from allanite by extraction chromatography using impregnated chromosorb

Water Resources and Industry, 2013
AbstractChromosorb 102 impregnated with Cyanex 923 was used as a stationary phase in the extraction chromatographic separation of lanthanides, U(VI), Th(IV) and Zr(IV). Batch studies were carried out to investigate the uptake behaviour of these metal ions, along with few other metal ions.

ESTIMATED MANUFACTURING COSTS FOR THE RECOVERY OF THORIUM AND URANIUM FROM MONAZITE SAND [PDF]

, 1950
Costs are estimated for the production of uranium and pure thorium from monazite concentrates. The process involves; reaction of the monazite with caustic soda, dissolution of the hydrous oxides in hydrochloric acid, separation from the bulk of the rare earths by hydroxide precipitation of thorium and uranium, and purification by solvent extraction ...

PROCESSES FOR RECOVERY OF URANIUM AND THORIUM FROM GRAPHITE-BASE FUEL ELEMENTS. PART II [PDF]

, 1961
Laboratory-scale tests on methods for recovering uranium and thorium from graphite-base reactor fuel elements are reported. The 90% HNO/sub 3/ process, which involves simultaneous disintegration and leaching in 21 M HNO/sub 3/, is applicable to all fuel elenments which do not contain coated fuel particles.
