Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the economic viability of the process.
In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or broken. Overburden or large rocks that are difficult to break through drilling are removed by the explosives to extract the limestone.
The process of limestone extraction involves separating the stone from the bench and dividing it into blocks. Get to know the procedures we employ.
