Abstract

Improvements introduced in the object of the main patent No. 370,363, granted on January 23, 1971, for "A procedure for the recovery of ammonia and carbon dioxide, as well as ammonium hydrogen fluoride from wastewater", characterized in that from wastewater containing (see formula), fluorine and exhaust gases that contain NH3 and CO2 =, especially from filtrates and exhaust gases that contain uranium from the CAU conversion, eventually to obtain calcium fluoride, a partial stream of the solution, now carbonate-free, obtained by reaction of the wastewater and/or exhaust gases with the strongly acidic solution of ammonium fluoride/ammonium hydrogen fluoride, is introduced, without concentration by subsequent evaporation, directly into a precipitation vessel, in which by the addition of ammonia and hydrogen peroxide a reaction takes place to form an insoluble uranium compound.
