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.)
