Lime Calcination SpringerLink
It is often applied in chemical processes in a slaked or calcium hydroxide or slurry form. The term “calcinations of limestone” refers to the process of thermal decomposition into quick lime and carbon dioxide. It is frequently referred to as “calcinations.”. Decomposition of limestone is characterized by very simple chemical reactions.

Dissolution rates of limestones of different sources
2000年12月1日 Most researchers found that reaction (1) is very fast, and some reported that the rate depends on the property of limestone [2], [7], [8]. Reaction (2) is instantaneous [9] ; its equilibrium constant is very large, 2.27×10 10 m 3 /kg mol at 298 K, thus almost all the carbonate ions are converted by this reaction in acidic solution.

Decarbonising the lime industry: State-of-the-art
2022年10月1日 The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes
