uranium ore processing uranium calcination
Improving uranium oxide pathway discernment and …
The combination of precipitating agent and calcination technique results in unique surface morphologies of the resulting uranium oxides, which investigators can use in determining the origin of an interdicted material as uranium processing facilities tend to use unique pathways to produce the desired UOCs, giving unique morphology "signatures".

Classification of uranium ore concentrates applying support …
The UOC powders contain about 60–80 % uranium in different chemical compositions (e.g. ammonium diuranate, uranyl hydroxide, uranyl peroxide, or uranium oxide when calcination is performed) (Kristo et al., 2016) and they are produced in large amounts, from which stems a risk of illicit appropriation. The illicit trafficking of nuclear ...
