titleOfInvention | Process for the recovery of a uranium-containing concentrate and phosphoric acid and uranium- containing concentrate and phosphoric acid obtained by this process |
abstract | ABSTRACT A uranium containing concentrate and phosphoric acid are obtained by digesting phosphate rock with H2SO4 and treating the H3PO4-solution -remaining after removal of calciumsulphate -, if so desired after evaporation, with a reducing agent, an organic dispersant and an inorganic F-compound, whereafter the resulting uraniumcontaining. precipitate is seperated off and phosphoric acid is recovered from the remaining mixture. As inorganic F-compound use is made of NH2F, which is prepared in situ by absorbing in water the gases escaping during the digestion and the optional evaporation, converting the H2SiF6-solution formed with NH3 to and SiO2-containing NH4P solution, separating off the SiO2 and applying the resulting NH4F-solution, for the uranium precipitation. |
