| dc.description.abstract | In this research, steel slag from steel and tube industries Uganda Ltd was used as a source of calcium for the production of calcium carbonate by carbonation process. Carbonation is a process of binding carbon dioxide into mineral carbonates (M. Owais, 2019) and in this case calcium carbonate was generated. In the process, steel slag was ground and calcium selectively extracted using ammonium chloride at varying concentrations of 0.5, 1, 1.5 and 2M. The resulting mixture was filtered and carbon dioxide bubbled through the filtrate to form precipitated calcium carbonate. The main objective was to produce precipitated calcium carbonate (PCC) and determine the optimum ammonium chloride concentration for calcium extraction. The results obtained show that as the solvent concentration was increased, the calcium extraction efficiency increased and the optimum concentration for the calcium extraction was found to be 1.5M ammonium chloride at 25˚C. Carbonation tests showed that increase in concentration of ammonium chloride increased the solubility of calcium carbonate and reduced the solubility of carbon dioxide and decreased the calcium conversion to calcium carbonate | en_US |
