·
OSTI ID:4241341
A method of recovering U from ore and converting it to oxide is given. In one example of the process 50 g of pulverized carnotite plus 100 ml of 1: 1 HNO/sub 3/ are digested at 100 deg C for 30 min, then evaporated to dryness. Four 50-ml ethyl ether extractions are made. The ether extract is then extracted with 3 2-ml portions of water which will contain some U and should be saved. The ether soln. of UO/sub 2/(NO/sub 3/)/sub 2/ can then be dried and ignited, or the UO/sub 2/(NO/sub 3/)/sub 2/ can be extracted into 3 or 4 20-ml portions of H/sub 2/O and dried and ignited.
