Download or read book Topical Report on Chemical Process to Recover Uranium from Phosphate Rock written by and published by . This book was released on 1948 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topical report describes progress made in chemical dissolution and recovery of uranium from phosphate rock. It covers approximately the period from November 15, 1947, to January 15, 1948, but the figures and other data are in part based on investigations since the start of this project. Two outstanding developments are: (1) an increase in the dissolution of uranium from the rock with sulphuric acid from about 55 percent to about 85 percent and (2) an increase in recovery of uranium from solution from about 50 percent to 90 to 95 percent. The increase in dissolution was obtained by calcining the rock prior to leaching. The better recovery resulted from use of larger amounts of amine in the precipitation. The indicated over-all recovery, not yet fully worked out on solutions from calcined rock, is about 80 percent.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were continued of a process for recovering uranium from wet-process phosphoric acid with octylphenyl acid phosphate (OPAP), a mixture of mono- and dioctylphenyl phosphoric acids. The mixture contained at least nine impurities, the principal one being octyl phenol, and also material that readily hydrolyzed to octyl phenol and orthophosphoric acid. The combination of mono- and dioctylphenyl phosphoric acids was the principal uranium extractant, but some of the impurities also extracted uranium. Hydrolysis of the extractant had little effect on uranium extraction, as did the presence of moderate concentrations of octyl phenol and trioctylphenyl phosphate. Diluent choice among refined kerosenes, naphthenic mixtures, and paraffinic hydrocarbons also had little effect on uranium extraction, but extraction was much lower when an aromatic diluent was used. Purified OPAP fractions were sparingly soluble in aliphatic hydrocarbon diluents. The solubility was increased by the presence of impurities such as octyl phenol, and by the addition of water or an acidic solution to the extractant-diluent mixture. In continuous stability tests, extractant loss by distribution to the aqueous phase was much less to wet-process phosphoric acid than to reagent grade acid. Uranium recovery from wet-process acid decreased steadily because of the combined effects of extractant poisoning and precipitation of the extractant as a complex with ferric iron. Unaccountable losses of organic phase volume occurred in the continuous tests. While attempts to recover the lost organic phase were unsuccessful, the test results indicate it was not lost by entrainment or dissolution in the phosphoric acid solutions. 21 figures, 8 tables.
