Cement manufacturing process and emissions. Cement is manufactured heating limestone (CaCO 3) with other minerals (alumina (Al2O3), silica (SiO2), and iron oxides (Fe2O3)) in a kiln and forms clinker.To produce cement, the clinker is grinded to fine powder and mixed with gypsum (CaSO 4. 2H 2 O). Several blended versions of cement …
