A Study of the Distribution of Impurities in the Extraction of Uranyl Nitrate with Ether from Aqueous Solutions

Description: Early in 1942 it had been found on a laboratory scale that certain impurities such as the Rare Earths were removed by small water washes from an ether solution of Uranyl Nitrate. It was hoped that in the large production units to be constructed that the water soluble impurities would all be washed out by the time the radioactive Thorium had been removed, so that the decrease in radioactivity could be used as an index of the amount of all kinds of impurity remaining in the ether layer.

The Determination of Uranium in K-65 (Gangue Lead Cake)

Description: The major problems in this determination are the extraction of X from the sample and the isolation of the extracted X. The application of various analytical methods to these two problems indicates that the current method of analysis yields values which may be as much as 15% high. The current method of analysis is subject to positive and negative errors. The magnitude of these errors varies with techniques and with sample composition. The recommend method, although longer, is believed to be free… more

Preparation and use of Ammonium Diuranate in the Ether Extraction Process

Description: In the ether extraction process, as originally developed, purified uranium dioxide was obtained by evaporation and calcination of the uranyl nitrate solution, followed by calcination of the resultant UO{sub 3}. It was suggested that an alternate procedure might be developed, involving the precipitation of uranium from the nitrate solution as ammonium diuranate. This material could then be calcined to uranosic acid, or reduced directly to the dioxide. It had already been established that ammoniu… more

The Distribution of Impurities in the Ether Extraction Process

Description: When uranium is purified by the ether extraction method, black oxide is dissolved in nitric acid and ether is added; an ether layer containing uranium and an aqueous layer containing uranium and impurities are obtained. The distribution of some impurities between the two phases and the effect of such impurities on the extraction process were studied. the processing required in the preparation of pure uranyl nitrate might be decreased if, instead of uranosic oxide, sodium diuranate was used as a… more
