Summary
Laboratory precipitation and filtration tests were performed to determine the conditions for producing an easily filterable uranium cake when NH/ sub 4/OH is added to a solution of UO/sub 2/(NO/sub 3/)/sub 2/. The laboratory investigation demonstrated that good conditions for production of a filterable uranium precipitate include a pH of 9.8 before filtration, addition of the NH/sub 4/OH to the UO/sub 2/(NO/sub 3/)/sub 2/ solution (in preference to addition of the UO/sub 2/(NO/sub 3/)/sub 2/ solution to NH/sub 4/OH), and an UO/sub 2/(NO/sub 3/ >i)/sub 2/ solution of a strength of about 160 g/l uranium. Concentrated NH/ sub 4/OH (28% NH/sub 3/) should be used at a precipitation temperature of 150 ts rF. Minimum aging prior to filtration is efficacious as are a stirring rate sufficient to maintain the precipitate in homogeneous suspension and a rate of agitation which will minimize localized pH changes. The results of an evaluation of filter cloths showed that nylon gives the best filtration rate and precipitate retention and has the best resistance to abrasion. (auth)
