Recent Technical Progress in the French Uranium Industry; LES RECENTS PROGRES TECHNIQUES DANS L'INDUSTRIE DE L'URANIUM EN FRANCE
Technical Report

OSTI ID:4039653
The present-day uranium production situation in France is reviewed. The various stages of the treatment that the concentrates receive, leading to the final production of the metal, are described briefiy: dissolution; purification by extraction with a mixture of tributyl phosphate and white spirit; precipitation with ammonia; drying and calcination of the trioxide; reduction with hydrogen, cracked ammonia, or preferably pure ammonia gas; fluorination with anhydrous hydrofluoric acid; and production of the metal by the calcium thermite process. Recent work of an original nature is discussed in greater detail. (auth)
