Uranium Extraction from Florida Phosphates

Nuclear Technology, 1981
The purpose of this paper is to present an overview of the various processes that have been used and are currently being employed for the recovery of uranium from Florida's phosphate deposits. The objectives of this paper are to describe the phosphate deposits in Florida with respect to approximate uranium content, teach something about the processes ...

Extraction of uranium and thorium from Swiss granites and their microdistribution. 1. Extraction of uranium and thorium

1983
This work is concerned with the extraction, at the laboratory level, of uranium and thorium from Swiss granites. The Mittagfluh, Bergell and Rotondo granites and the Giuv syenite offered a wide range of U and Th concentrations: 7.7-20.0 ppm U and 25.5-67.0 ppm Th.

Uranium extraction by complexation with siderophores

2016
One of the major concerns of energy production is the environmental impact associated with the extraction of natural resources. Nuclear energy fuel is obtained from uranium, an abundant and naturally occurring element in the environment, but the currently used techniques for uranium extraction leave either a significant fingerprint (open pit mines) or ...
