Abstract


In this work it had been tested the recovery of some compounds like: Fe2O3, TiO2, PO43-ions, Al2O3 from the sludges, which result in the industrial facilities for output of pure uranium dioxide. Solubilization of the chemical compounds from the uranium wastes was performed in strong acidic media, using adequate methods.
