A STUDY OF THE SALTING IN OF BARIUM AND LEAD SULFATES BY CHEMICAL AAA PITCHBLENDE LIQUORS AND PURE URANYL NITRATE SOLUTIONS
In the precipitation of BaSO/sub 4/ from UO/sub 2/(NO/sub 3/)/sub 3/ solution s the effect of supersaturation accounts for only 2 to 5% as much BaSO/ sub 4/ retained in solution se does the salting-in effect of the UC/sub 2/(NO/sub 3)/sub 2/. The use of salting agents added to facilitate the ether extraction of the UC/sub 2/(NO/sub 3/)/sub 2/ has marked effects upon the precipitation of both BaSO/sub 4/ and PbSO/sub 4/ from the raffinates. The use of Fe(NO/sub 3/)/sub 3/ as the added salting agent gave considerably better precipitation characteristics than did a 1:1 mixture of Fe(NC/sub 3/)/sub 3/ and Ca(NO/sub 3/)/sub 2/. Th e use of Fe alone permitted only 7.1% as much BaSO/sub 4/ to precipitate immediately and only 80.7% as much total precipitation over a 24 hr period as did the use of the 1:1 mixture of salting agents.
