production process of grounded limestone

Missouri Limestone - Missouri Department of Natural Resources

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.

Ground Calcium Carbonate (GCC)

Limestone formations are formed by natural precipitation, a process that occurs slowly. This is part of the explanation why the material in limestone products is completely converted to the CaCO3 form. By contrast, depending on the conditions of its production, precipitated calcium carbonate may contain some residual calcium hydroxide.

Emissions from the Cement Industry

May 09, 2012  The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.
