Answer: Limestone deposits are found throughout the world. They are “mined” in a process known as “quarrying.” This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined. In this case, the rock has h...

Limestone Mining Methods Today, as in the past, the most demanding task of limestone mining was the cutting and lifting of the blocks of stone out of the ground, then hauling them to the mill. As has been said, it was not just the high quality of the limestone that developed the industry here, but the rock was close to the surface.
