Separation and Extraction of Uranium from Leach Liquor Containing Uranium and Molybdenum by Solvent Extraction with LIX 622N

Journal of Dispersion Science and Technology, 2014
The leach liquor (0.5 g/L Mo, 0.05 g/L U) obtained from the leaching process of molybdenum-uranium ore material was treated using solvent extraction to recover U(VI) by LIX 622N, which is a salicylaldoxime derivative. The influence of various basic variables such as pH, concentration of LIX 622N, temperature, different stripping reagents, phase ratio ...

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 ...

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 ...

Spectrophotometric Extraction Methods Specific for Uranium

Analytical Chemistry, 1959
Two spectrophotometric extraction methods specific for uranium are described. Uranium as tetrapropylammonium uranyl trintrate is quantitatively separated from large quantities of diverse ions by extraction into methyl isobutyl ketone (4-methyl-2-penthnone) from an acid-deficient aluminum nitrate salting solution.

Uranium Recovery by the Solvent Extraction Process

JOM, 1957
Mills employing the sulfuric acid leaching method for uranium have been confronted with a major problem in recovering uranium from leach solutions, but today, solvent extraction offers a new method of processing these leach solutions. During the past year, the industry has seen the operation of solvent extraction circuits at the Climax Uranium Co. mill
