| Abstract | ||
| Phosphate plays a significant economic role in developing countries because the phosphate rock is consumed in the agricultural sector as fertilizers and animal feedstocks as well as used in the manufacture of high-grade phosphoric acid used in the manufacture used in pharmaceuticals, detergents, food products and other industrial uses. So, this research focus is represented in how to apply some new physical concentration processes derived from ore dressing to arise the concentration of P2O5 (21.14%) in sample of 10 Kg of low grade Egyptian phosphate ore was collected from East El-Sibaeya region as an alternative method to the existing calcination method, which is not friendly environment and has several disadvantages and accordingly the find relationship between the uranium concentration and the upgrading of El-Sibaeya phosphate ore. Upgrading the phosphate ore is done through crushing, screening, up current Classifiers, gravimetric separation and hydraulic separation. The results of this study led to achieve the desired product (high grade of phosphate) which is imperative to meeting market requirements, and at optimum conditions gave a product which analyzed P2O5 (33.63%), CaO (47.66%), MgO (0.57%), SiO2 (4.91%), NaO2 (0.49%), K2O (0.89%), Al2O3 (0.64%), Fe2O3 (1.25%) and U (172.12 ppm). | ||
