The US Bureau of Mines, under an Interagency Agreement with the Department of Energy, conducted characterization studies on the extraction of uranium from a Red Desert, Wyoming, carbonaceous silty mudstone. The characterization study included acid and carbonate leaching, roasting, autoclaving, pugging, and ferric salt leaching tests. The various leach processes tested produced 87% U/sub 3/O/sub 8/ extraction using the acid amenability process, 67% using the carbonate amenability leach process, and 83% using the roast and leach process. A cost study would be necessary to determine the economic feasibility of using this ore body for future uranium production. 11 tables.
