Abstract :In marine phosphate of şafağa, Egypt, tetravalent Uranium, Uinsert ignore into journalissuearticles values(IV); is found to be between 70 to 80 % of the total uranium. However, the phosphatic sandstone of Qatrani, Egy¬pt, is nearly devoıd of Uinsert ignore into journalissuearticles values(IV);. As shown by autoradiographs, uranium is mainly concentrated in the carbonate Fluorapatite, Francolite or Collophane minerals. The Uinsert ignore into journalissuearticles values(IV); and Uinsert ignore into journalissuearticles values(VI); content of process solution samples during phosphoric acid produc- tion are obtained. Firstly by dissolving the samples by hydrochloric acid under normal conditi- ons. Secondary by dissolving the samples in an oxidizing atmosphere. The uranium concentra- tion is determined by fluorimetry. The achieved results are presented and found to be in good agreement with that obtained by tri-n-octylamine extraction and polar-ography
