Abstract

Method for removing dissolved fluorides from an aqueous solution of wastes from a uranium fuel manufacturing plant from uranium hexafluoride in the presence of ammonia, characterized in that the solution contacts metal carbonate particles alkaline earth, said particles having at least 75% by weight, a grain size exceeding 0.08 mm., by adding particles to the solution or passing the solution through a bed of particles, the Reaction between the particles and the solution is carried out at a temperature of at least 50ºC, forming from the carbonate particles, particles of an alkaline earth metal fluoride that has substantially the same grain size as the carbonate particles, subsequently it is they separate the alkaline earth metal fluoride particles and the solution.
