Calcium thermic reduction waste
WebCalcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate http://cje.ustb.edu.cn/en/article/doi/10.13374/j.issn2095-9389.2024.12.14.002
