What is the limestone's mining process? - Quora
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...
