Abstract: Good quality of huge limestone beds are found in many parts of N.W.F.P, Pakistan, particularly in Khyber Agency, Kohat and Cherat Areas. Limestone samples were collected from different localities of these areas for chemical analysis. Results of different areas were compared to each other for the industrial utilization. The chemical composition of the deposits of all the three areas indicate that these deposits would be utilized for production of cement, refining of sugar, glass, ceramic, paper and chemical industries. Percentage of lime was found to be in the range of 31.18-55.10, 38.61-53.05, 44.28-54.42% and average percent composition of SiO2 is 1.45, 3.82, 3.75%, Al2O3, 0.76, 1.157, 0.71%; Fe2O3, 0.34, 0.44, 0.415%; TiO2, 0, 0, 0%; MnO, 0, 0, 0%; P2O5, 0.008, 0.004, 0.024%; CaO, 48.30, 49.77, 52.284%; MgO, 5.60, 2.80, 0.366%; Na2O, 0.23, 0.15, 0.439%; K2O, 0.056, 0.07, 0.227%; SO3, 0.003, 0.002, 0.001%; Cl-, 0.002, 0.001, 0.003%; moisture, 0.065, 0.08, 0.095% and l.O.I, 43.25, 41.97, 41.47% in Khyber Agency, Kohat and Cherat Areas, respectively.
