Surface quarrying is the most common method of producing limestone in Missouri.
Limestone and Lime – IspatGuru
Limestone when heated starts decomposing into lime (CaO) and carbon di-oxide (CO2) at 810 deg C. The process is called calcination of limestone. It is a thermal treatment process which is carried out for the thermal decomposition of the raw limestone for the removal of LOI (loss on ignition) or carbon di-oxide (CO2) part of its composition.
