A process is proposed for the treatment of phosphate rock for the recovery of uranium and the lanthanides. The process is based on the use of nitric acid for leaching the rock, the use of common reagents for the recovery of fluorine and the removal of radium, and the use of organic solvent for the recovery of uranium and the lanthanides. The process assures the production of phosphatic fertilizers without polluting the environment with radioactive material. While many processes for uranium recovery from phosphoric acid produced by the H2SO4 route are known and utilized commercially, little is known about uranium recovery from phosphoric acid produced by the HNO3 route. Advantages of the latter route are both the elimination of the gypsum disposal problem and the possibility of radium disposal in a controlled way. Further, the lanthanides originally present in the rock can be recovered if the nitric acid route is used; they will be mostly lost in the gypsum produced by the sulphuric acid route. In the present work a scheme for the recovery of uranium and the lanthanides from phosphate rock without interfering with the normal route for fertilizer production is proposed using HNO3 as a leaching agent.
