2022-1-5 · Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock. rough crushing. After crushing the stone is sorted into different fractions by screening, after which it goes to be processed further. In the grinding process the limestone is ground to a fine powder.
Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones. The water pressure compacts the sediment, creating limestone.
