The extraction method for limestone is typically done through open-pit mining or quarrying. In open-pit mining, a large hole is dug in the ground and the limestone is extracted using heavy machinery such as bulldozers, front-end loaders, and haul trucks. In quarrying, the limestone is extracted by cutting blocks or slabs of rock from the deposit using saws, diamond wire cutters, or drilling equipment. The extracted limestone is then crushed and transported to a processing plant for further refinement.
