Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Extraction 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.
