ABSTRACT
Investigations were carried out for geochemical characterization of Sokoto Phosphate rock and to propose a suitable ore dressing process for the recovery of phosphate for fertilizer and allied applications. The study area is Iullemmeden Basin (Sokoto sector) in the Northwestern geopolitical zone of Nigeria. The phosphate rock occurs mainly in nodules, while some are found as pellets, especially in the southern part of the study area. The phosphate deposit occurs predominantly in the Dange Formation and a small occurrence in the Gamba Formation. The phosphatic nodular beds measure between 0.3 m and 0.1 m, while the nodular disseminations may be up to 6 m in thickness. The P2O5 values range from 20.18-36.25 wt. %, while the Jordan, Morocco, USA, Algeria, China and Syria phosphates have the range of 30-35 wt. %. A mixture of di(2-ethylhexyl) phosphoric acid (DEPA) and tri-octylphosphine oxide (TOPO) is proposed for the recovery of uranium from phosphates.
