Study of the physical properties of aluminothermic slags for the recovery of uranium and thorium
Brazilian Journal of Radiation Sciences, 2021 NORM minerals generate, after metallurgical processing, radioactive slags that can be controlled by CNEN. Thus, it is necessary to establish a reprocessing route to make the material exemption. The route necessarily passes through the characterization of

RECOVERY OF THORIUM FROM A WYOMING ORE [PDF]
, 1961 An investigation of Bald Mountain, Wyo. ore was conducted in which it was found that the monazite concentrate prepared from this conglomerate can be decomposed by the conventional sulfuric acid-cure treatment. The resultant acid leach liquor can be processed by primary amine solvent extraction to yield a 99% ThO/sub 2/ product. (J.R.D.)
