Thorium metal is slowly attacked by dilute hydrochloric, hydrofluoric, sulfuric, or nitric acids. It dissolves readily in concentrated hydrochloric acid or aqua regia. It is passive in concentrated nitric acid, but dissolves readily if 0.05 M of fluoride ion is added. This would be the preferred reagent to prepare feed for reprocessing irradiated thorium metal by the Thorex process. [Pg.289]

See other pages where Thorex process irradiated, dissolved is mentioned: [Pg.234] [Pg.955] [Pg.94] [Pg.955] [Pg.516] [Pg.7100] [Pg.7219]
