What is Calcium Carbonate Limestone? | Carmeuse
Calcium carbonate's most common natural forms are limestone and marble. These raw materials are mostly produced by the sedimentation of the shells of foraminifera, brachiopods, bryozoan, snails, shellfish, corals and other organisms that took place many millions of years ago. Although the many varieties of limestone (such as chalk) and …
