In the United States, Indiana, most notably the Bloomington area, has long been a source of high quality quarried limestone, called Indiana limestone. Many famous buildings in London are built from Portland limestone .
In locations where geologic and market stipulations authorize, limestone for collective is mined from underground mines. Despite the fact that mining is more expensive than quarrying, the underground mining of mineral can be a combination of both economical and necessity in some areas of the state.

Limestone, composed mostly of calcium carbonate, is used primarily to produce Portland cement for the building industry. Other products that use limestone include breakfast cereal, paint, calcium supplements, antacid tablets, paper and white roofing materials.
Limestone Rock Uses, Formation, Composition, Pictures
GeologyLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is where organis

Relation to Mining
UsesLimestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earths sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite. As a source for lime, it is used to make paper, plastics, glass, paiSee more on mineralseducationcoalition
Environmental Hazards of Limestone Mining Education
Limestone mining can affect ground water conditions. Limestone deposits often occur in association with karst, a topography where limestone slowly dissolves away underground. The deposits result in sinkholes, caves and areas of rock fractures that form underground drainage areas.
Limestone The Calcium Carbonate Chemical Sedimentary Rock
Mission\quot;Limestone\quot; means any rock formed mostly of calcium carbonate (CaCO3), but to geologists, limestone is only one of several types of \quot;carbonate rocks.\quot; These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO3) or dolomite (calciummagnesium carbonate, CaMg[CO3]2) or both.See more on geology
What is the limestone's mining process? Quora
Jan 30, 20170183;32;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.

Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

limestone mining Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
