Abstract
This study is related to the work on beneficiation of raw phosphates by thermal processing (selective vaporization). More precisely it deals with the ability of a calcium-aluminium phosphate (ores from Thies) to vaporize selectively as phosphorus pentoxide and uranium contents. Experiments are performed on liquid samples at Tsub(f)<2000/sup 0/C in vacum (p < 1 torr) or in air. Both uranium and phosphorus pentoxide vaporize quite selectively up to 1600/sup 0/C with approximately the same rate of vaporization. At higher temperatures only calcic and aluminous compounds remain as stable phases in the residuum.
