Abu-Tartur plateau are exploited by open cast of a layer ranges in thickness between 3.9 to 4.5 meters. The average P2O5 content is 24%. The impurities are mostly iron and magnesium carbonates with low silica content. Therefore, the beneficiation step is mandatory to produce a phosphate concentrate for merchant grade phosphoric acid and phosphate fertilizers. In this study, five flow sheets with different setup and machineries were tested and compared to the current flowsheet at the Misr phosphate company. Each flowsheet was tested technically in terms of grade and recovery of the produced concentrate and economically in terms of the cost of the produced ton of concentrate with the required grade. A concentrate containing 30% P2O5 was obtained at a cost ranges from 183 to 212 Egyptian pounds per ton. The main result is the same concentrate can be produced by about 30 pounds less in cost by selection of the proper flowsheet and machinery
