limestone quality is determined based on the desirable oxides of calcium, silica, aluminum, and iron i.e. CaO, SiO2, Al2O3, Fe2O3 [1]. Limestone also contains some undesirable oxides like MgO, SO3, K2O, Na2O, and P2O5, etc. The raw mix for the cement plan is dependent upon the quality of limestone mined at a specific period.
