Abstract
A chemical procedure is described for the treatment of the filtrate, produced from the transformation of uranium hexafluoride (U F{sub 6}) into ammonium uranyl carbonate (AUC). This filtrate is an intermediate product in the U F{sub 6} to uranium dioxide (U O{sub 2}) reconversion process. The described procedure recovers uranium as ammonium peroxide fluoro uranate (APOFU) by precipitation with hydrogen peroxide (H{sub 2} O{sub 2}), and as later step, its calcium fluoride (CaF{sub 2}) co-precipitation. The recovered uranium is recycled to the AUC production plant. (author).
