Uranium recovery from strong acidic solutions by solvent
Introduction. Uranium is a naturally occurred nuclide used for nuclear power generation. From uranium ore to nuclear fuel, solvent extraction technology plays an essential role for its recovery and purification (Edwards and Oliver, 2000, Lunt et al., 2007, van Tonder and Kotze, 2007, Zhu and Cheng, 2011).
Solvent extraction Solvent extraction is widely used in the ex- traction of metals using specific, chelating, sol- vating or liquid ion-exchange reagents. Many re- searchers used organo-phosphoric agents in kero- sene [9–11], 8-hydroxyquinoline in chloroform [12] or using diethyl ether [13] to extract uranium from seawater.

1. Introduction. Uranium is a naturally occurred nuclide used for nuclear power generation. From uranium ore to nuclear fuel, solvent extraction technology plays an essential role for its recovery and purification (Edwards and Oliver, 2000, Lunt et al., 2007, van Tonder and Kotze, 2007, Zhu and Cheng, 2011).
Uranium solvent extraction, USX has been applied commercially for recovery and concentration for over 60 years. Uranium in acidic liquor, which is prepared following ore leaching, solid/liquid separation and clarification, can be treated through a sequence of operations; extraction-scrubbing-stripping, to obtain purified liquor, and hence precipitation of marketable products.
Extraction of uranium from the concentrated brine rejected by
Although resins exhibit fast kinetics, they offer very poor selectivity for uranium. Solvent extraction is a well-confirmed method for specific metals, but the solvent may be lost due to
In terms of energy resource recovery and environmental protection, the separation of U(VI) from aqueous solutions is vital. Adsorption and solvent extraction are the most common separation technologies, which are also widely used for uranium recovery or removal from aqueous solution. The linear structure of uranyl ion and its multiple coordination feasibilities offer great opportunities for
SOLVENT EXTRACTION OF URANIUM( VI) AND THORIUM( IV) FROM
Increasing steric bulk of the alkyl groups R and R' was found to cause a marked decrease in the extraction of thorium, with a much smaller effect on the extraction of uranium, thus considerably enhancing the separation between these metals.

With an eye on the different extractants or solvent systems that were studied earlier for uranium extraction from phosphoric acid, factors affecting the extractant moiety are also reviewed to provide insight upon emerging novel extractants to be explored in the future endeavor of solvent designers or synthesizers.
What is uranium solvent extraction (SX)?
Uranium solvent extraction (SX) from aqueous acidic solutions is reviewed. First the uranium availability in earth as well as resources, mining and production reports is presented and followed by SX basic flowsheet and various important stages. Extraction, scrubbing, stripping and finally solvent equilibrium are presented in a flow-sheet form.
What is solvent extraction and ion exchange?
Solvent extraction and ion exchange are well developed and commercially used processes of separation of uranium from post-leaching solutions. Treatment involves removal of associated metals, such as molybdenum, vanadium, iron, arsenic, zinc, copper, nickel and rare earth elements.
How is uranium recovered from phosphate ore in Sudan?
Abdelmajid et al. (2014), investigated the uranium recovery from phosphate ore from the Uro region in Sudan . Initially, the phosphate ore samples were digested with concentrated nitric acid. The phosphoric acid was produced from the resulting powder with the aid of sulfuric acid at 80?¡ãC. 4.2. Alkaline extraction
What extractants are used for uranium extraction?
The second half of the review discusses the various extractants used for uranium extraction and separation from acidic solutions. The extractants are divided in four types: 1) nitrogen-based extractants, 2) phosphorous-based extractants, 3) sulfur-based extractants, and 4) other extractants.
