Recovery of uranium-233 from a thorium breeding blanket by pyrochemical techniques [PDF]
, 1982 We have carefully evaluated several processes that might be suitable for uranium recovery from thorium metal, and have chosen two that hold great promise. Both are simple non-aqueous methods that can readily be performed by remote means, and both require only a few simple process steps.

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.

Thorium Between Removing, Recovery and Recycling: A Membrane Challenge for Urban Mining
, 2023 Although a slightly radioactive element, thorium is considered very toxic because its various species, which reach the environment, can constitute an important problem for the health of the population. The present paper aims to expand the possibilities of using membrane processes in the removal, recovery and recycling of thorium from industrial ...
