In Sri Lanka limestone occurs in various forms, including: Miocene limestone (over 95% CaCO 3) Coral (over 95% CaCO 3) Shell (over 95% CaCO 3) Dolomite (MgO (variable 8% -21%)) Calcite (CaCO 3 ( pure)) Miocene limestone is mainly consumed in the cement industry. Calcite: is limited in its occurrence and is used in the ceramic industry.
