For well over a century, Missouri has hosted a robust limestone industry that has mined the rock and processed it into a variety of useful, if not vital, products for Missouri, the nation and the world. Limestone . The burning of limestone in the cement-making process liberates carbon dioxide gas (formula CO2). Limestone is

Limestone. A foremost element of the mining process is breaking up the rock. This breakup is accomplished by detonating volatiles set in blast holes. The rock face to be gusted is typically 40-feet in width by 20- to 25-feet high. A premeditated pattern of 40 to 50 horizontal holes are drilled for the dimensions of 2 inches wide

Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together, or it can fill fractures.

Limestone is a very common type of rock that is made mostly of calcite with minor amounts of silt and sand. It is commonly interbedded with layers richer in In the smelting of other metals, limestone also combines with impurities, allowing them to be removed from the process as a slag.

Compare the above maps to the map below, which shows where limestone is mined or excavated. Notice that the mines are loed near major transportation arteries, or on the Great Lakes proper. This is because these rocks, like many rocks, are so heavy that they do not bear the cost of transportation well. That is, they

Quarry: Quarry, place where dimension stone or aggregate (sand, gravel, crushed rock) is mined. The products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate. After cutting and polishing, these materials are used in the primary construction.
