Pollock, E N

A method is described of producing green salt (UF/sub 4/) from uranium-bearing metal pieces comprising: dissolving the uranium-bearing metal pieces in a first aqueous solution containing hydrochloric acid and at least 0.5% but no more than 2% fluoboric acid to provide a second aqueous solution which includes uranium (U/sup +4/), chloride ions and hydrochloric and fluoboric acids; adding hydrofluoric acid to the second aqueous solution to precipitate green salt out of the second solution and provide a third aqueous solution containing hydrochloric acid; and separating the green salt from the third aqueous solution.
