Cosmic Origins of Uranium - World Nuclear Association

It is likely that since about 2.5 billion years ago injections of uranium into the mantle have been effective in the reduction of the thorium to uranium ratio on an (upper) mantle-wide scale. An additional net effect is the selective reinjection of uranium as opposed to lead – which is mostly stripped out in subduction zones and returned immediately to the crust – into the mantle.

Enrichment and Encapsulation of Uranium with Iron …

The ability to recover uranium from water is significant because of its potential appliions on nuclear fuel capture and mitigation of nuclear wastes. In this work, a unique nanostructure is presented by which trace level (2.32–882.68 μg/L) uranium can be quickly separated from water and encapsulated at the center of zero-valent iron nanoparticles. Over 90% of the uranium is recovered
