The low impurity concentration range was o.i2-o.0o /^g/g U, and the liigli impurity concentration range was 5.0-52.5 /^g/g U; 20 g of uranium was used for cadi standard at tlie low concentration level, and the atomic absorption analyses were performed on 10 ml of solution. For the high concentration level of impurities, 8 g of uranium was taken, and tlie atomic absorption analyses were ...

In the given paper the centrifugal laboratory extrac tors EC33 produced at pilot plant NIKIMT in Moscow were applied for processing concentrated solutions of uranium with high content of impurities. Some technical features of EC33 are ...
Most impurities present in the uranium leach solution are not extractable with tertiary amine as they do not form or form very weak anionic complexes with 2 SO4. These impurities include Fe(III), Al(III), RE(III), V(V) and divalent metal ions etc. The selectivity of tri-isooctylamine (TIOA) for different ions was reported by Coleman et al. (1958) as shown in Table 1. 0.1 M TOA, 0.01 M U in ...

15/09/2012 The solution obtained after separation is purified in uranium and the uranium decontamination was checked by ICP-MS measurement. As a result, up to 99.997% uranium was eliminated. All impurity measurements, which were in 10 mL of the acid mixture, were performed using a diluted acid (typically by a factor of 4) to be more suitable with the ICP-MS. This procedure was
elements present as impurities. Uranium can be extracted from several dilute acids, as sulfuric, hydrochloric, phosphoric, acetic, oxalic, hydrofluoric, formic and maleic by long chain amines, as for instance with MDOA-xilene*3''1, or even extracted from dilute sulfate solutions116'. This paper is presented as a contribution to the selective solvent amine extraction of uranium from ...

Alkaline solutions tend to be more selective to uranium minerals, which means the solution will contain fewer impurities. Consequently, the uranium oxide (commonly called "yellow cake") can be directly precipitated without purification. Furthermore, the solutions are less corrosive and ...
Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
mining-solutions.basf EVG1254e Uranium Solvent Extraction. BASF technology for the recovery of uranium from acid leach solutions History The Mining Solutions unit of BASF (formerly Cognis) has been intimately involved in uranium processing technology since 1957. That was when we introduced Alamine® 336 to the mining industry as the first commercially available tertiary amine
The uranium in solution is recovered in a resin/polymer ion exchange (IX) or liquid ion exchange (solvent extraction – SX) system. The pregnant liquor from acid ISL or heap leaching is treated similarly. Further treatment for IX involves stripping the uranium from the resin/polymer either with a strong acid or chloride solution or with a nitrate solution in a semi-continuous cycle. The ...

The volume rate of water:uranium concentrate in the rinse system must be between about 15:1 to 5:1, in order to effectively pass, flush out and recover substantially all of the remaining phosphoric acid as dilute solution, which will be substantially free of iron and organic impurities, and thus useful for further processing and resale.
trace level impurities in uranium matrix by ICP-OES is not successful due to spectral interferences caused by the line-rich emission spectrum of uranium [11–13]. Contamination of equipment due to direct injection of high uranium salt solution into ICP-OES is another restriction. Hence, an efficient separation technique for the selective removal of uranium from the trace impurities is an ...
