What is the method of extraction of limestone? - Docsity
Limestone is a sedimentary rock composed of calcium carbonate (CaCO3). Limestone comes from the shells of dead marine organisms such as clams, oysters, crayfish, brachiopods, bryozoa, crinoids and corals. Such animals live on the bottom of the sea and after death their shells accumulate into piles, forming beds of limestone.
