All over the world, limestone is generally mined from a quarry or through open-pit mining. This method is the easiest way to remove limestone without causing much destruction. In surface mining or open-pit mining, the topsoil and overburden covering the mineral are removed. Then, through the process of drilling, the rocks are broken.
