| Abstract | ||
| In view of the availability of a cheap and a high quality limestone raw material and the practical abilities to produce precipitated calcium carbonate (PCC) using the carbonation process route, this study was carried out with bench scale experiments. High purity limestone of Wadi Ghadaf (Dammam Formation), was calcined to produce quick lime which was converted to calcium hydroxide by slaking with water, the final stage comprised injection of CO2 gas into the slaked lime slurry. Calcium carbonate was precipitated as a high purity (99.5% CaCO3) white powder (95% brightness) with a particle size range of (6 – 12) microns. Conditions optimization was done through each stage of this study. | ||
