Study of the geochemical analysis of Mbatiav limestone deposit for the production of cement was carried out to ascertain the suitability of the limestone deposit for the production of cement. Core samples from different holes were analysed for oxides and alkalis using X-Ray Fluorescent photometer (XRF). Chlorides were determined using Silver Nitrate (AgNO3) potentiometer titrations while sulphites were determined using gravimetric methods and using Barium chloride (Bacl2) as the precipitating agent. The results of the geochemical analysis showed that the deposit contained high grade limestone with CaO percentage ranging from 42.96% – 49.06%, with an average of 46.66% for subsurface samples, and 37.84% – 51.14%, with an average of 43.72% for outcrops. In general, the results showed that the limestone deposit satisfy the CaO and other contents for cement production, provided SiO2, Al2O3, and Fe2O3 contents satisfy the ultimate moduli values of raw mixes.
