Excavation of Limestone | SpringerLink
Limestone is found near the surface (called a surficial deposit); hence, it is produced mainly from surface mines.By and large, limestone is mined by two methods: opencast stripping for hilly deposits and open-pit mining for plain deposits. To meet the industrial requirements of a large country like India, medium- and small-sized mines of …
Production
The whole process of making any type of lime all begins at the limestone quarry after careful surveys. Most limestone is extracted through blasting. Behind the rock face, holes are drilled to place the explosives. When detonated, the explosion dislodges each time up to 30,000 tonnes of stone.
How Limestone is Formed
Chalk is a fine-grained, porous limestone while travertine is a freshwater, more sedimentary limestone that has thin layers. Marble is also a carbonate rock that has been squeezed down and formed into a different material with heat and pressure. Mining Limestone. Limestone deposits can be huge and cover hundreds of square miles. It's …

quality of the limestone feed to the plant. Often these deposits contain anticlinal or synclinal folding; faulting; blocking; and, other geologic structures that make mining difficult. The more complicated the limestone structure, the more sampling and testing required to ensure the delivery of quality limestone to the process.
How Lime is Made
Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate), along with minerals. Lime production begins by extracting limestone from quarries and mines. Sizing . . . Limestone enters a primary crusher to break the rock.
