Recovery of Thorium by High-Capacity Biopolymeric Sorbent
Separation Science and Technology, 2013 The potential of prepared alginate biopolymers as a natural, economic, effective, non-toxic biosorbent was investigated for the recovery of thorium ions in this study. The experiments were carried out to study the effects of various physico-chemical parameters on biosorption and desorption of thorium.

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.)
