Galvanek, P Jr

A new lyometallurgical method for extracting uranium from ores is described. The method involves static suifuric acid-digestion at high solid-to- liquid ratios, treatment with calcium salts followed by leaching of the damp slurry with plain or nitric acid-containing acetone-ether or alcoholether mixtures. Very little nttrate is left in the residue. Nitric acid requirements are reduced through the use of calcium salts, in some instances being eliminated entirely. Uranium extractions ranged from 84 to 98% on Marysvale, cupriferous- uranium, and carnotite ores. Alumina may be used to remove impurities from pregnant solvents prior to uranium precipitation. Products assaying over 99.8% U/ sub 3/O/sub 8/ have been obtained after alumina treatment. (auth)
