Uranyl sulfate | UO2SO4 - PubChem

Approximately 60% of uranium absorbed into the blood is transported in the form of a bicarbonate complex, and 40% is bound to plasma proteins. The uranyl-bicarbonate complex is filtered out of the blood by the renal glomerulus and is passed into the tubules.The pH of urine decreases in the tubules, resulting in dissociation of the complex and release of the reactive uranyl ion.

Uranous sulfate is known to crystallize from uranium(IV) sulfate solutions upon the addition of sulfuric acid and the application of heat. This phenomenon, when coupled with a prior reduction process, could be exploited as a new way to selectively separate uranium from impurities in a high-grade leach solution.

Sodium diuranate - Wikipedia

Sodium diuranate, Na 2 U 2 O 7 ·6H 2 O, is a uranium salt also known as the yellow oxide of uranium. Sodium diuranate is commonly referred to by the initials SDU. Along with ammonium diuranate it was a component in early yellowcakes. The ratio of the two compounds is determined by process conditions; however, yellowcake is now largely a mix of uranium oxides.
