Uranium may be recovered from solution by any of the following methods: a simple precipitation, three methods of obtaining iron-free precipitates, or ion exchange. MgO or calcined dolomite may be used with each of the precipitation methods. For retreatment, the precipitate may be leached with Na/sub 2/CO/sub 3/ or, after nitration, with ether, or it may be redissolved by either of two methods which reject silica. After dissolution, precipitation as peroxide, as pyrophosphate, or as hydroxide yields a high-grade product. Additional testing and economic calculations are planned to select the best method for obtaining high-grade product from Rand leach liquors. (auth)
