Missouri Limestone Missouri Department of Natural

The pelletal material exiting the kiln is called “clinker. ” Gypsum is added, and the clinker-gypsum mixture is finely ground into Portland cement. The burning of limestone in the cement-making process liberates carbon dioxide gas (formula CO2). Limestone is used in the manufacture of three kinds of lime that have a wide range of uses.

Calcium looping Wikipedia

2021-4-15  Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
