In this work, the suitability of phosphate ore treated with the varied salts such as FeSO{sub 4}, NaCl, CaCl{sub 2}, Na{sub 2}SiO{sub 3}, and Na{sub 2}SO{sub 4} as an alternative material for limestone and dolomite in flue gas desulfurization has been investigated. Also, the effect of the varied salts on calcination and sulfation of the raw, calcine, and semicalcined phosphate samples has been investigated in a differential fluidized bed reactor at 700-800{sup o}C (4 min) in air and 0.3% SO{sub 2}. It was established that the salts have prominent effects on sulfation and calcination. The changes in the pore structure and products obtained at the end of sulfation were investigated using BET surface area method. In conclusion, it was observed that the sulfation and calcination conversion ratios generally increased when the phosphate rock was treated the varied salts.
