Uranium Recovery from Phosphates for Self-Sufficient Nuclear Power in the Eastern Mediterranean

Science and Technology of Nuclear Installations, 2022
Production of phosphate fertilizers (PF), without uranium recovery, amounts to dispersing uranium compounds on agricultural fields. These compounds are naturally hidden in phosphate rock deposits prior to processing.

Uranium(III)-carbon multiple bonding supported by arene δ-bonding in mixed-valence hexauranium nanometre-scale rings

Nature Communications, 2018
Owing to the propensity for uranium(III) compounds to undergo disproportionation, uranium-element multiple bonds involving uranium(III) oxidation states remain rare. Here the authors report hexauranium-methanediide rings that formally contain uranium(III)

Influence of geochemical factors on uranium migration during in-situ leaching [PDF]

E3S Web of Conferences
In-situ leaching is one of the most efficient methods for the development of sandstone-type uranium deposits. The efficiency of the process is determined by geochemical mechanisms of uranium mineral dissolution, oxidation of tetravalent uranium, and the ...
