crushed and broken limestone, including related rocks, such as dolomite, cement rock, marl, travertine and calcareous tufa.
Calicite is mined in same way that limestone is mined which entails just collecting the deposits. However, the production s quite an involving process which starts with the separation of different grades and removal of unwanted impurities. It is then crushed and subjected to froth flotation.
Limestone is one of the most common types of rock mined using a quarry. It is widely used in construction, agriculture, and as a raw material in manufacturing industries.
Rocks are mined in a quarry by blasting or drilling to break up the rock into manageable pieces. Heavy machinery such as excavators and dump trucks are then used to extract the rocks from the quarry. The rocks are crushed and processed for various uses in construction or manufacturing.
The process is called calcination or lime-burning. This mined from the Wikipedia article on calcium oxide. A link is provided.
Limestone is primarily composed of the mineral calcite (calcium carbonate), which is its main ore mineral. In some cases, limestone can also contain other minerals such as dolomite (calcium magnesium carbonate) and aragonite. While limestone itself is not typically mined for metals, it is a valuable source of calcium for various industrial applications and can serve as a raw material in cement production. Additionally, impurities in limestone can include clay, silica, and iron oxides, which can influence its uses and properties.
In the past most crushed and broken stone has been mined from open quarries. Today, the trend has been more toward underground mining.
Coal, oil and natural gas are mined in Tennessee. Tennessee mines ball clay which is used primarily in the manufacture of dinnerware, floor and wall tile, and pottery. Crushed stone, limestone, clay and zinc are mined in Tennessee.
Bituminous coal and limestone are mined in Indiana.

Limestone can be found in many parts of the world and is usually mined in surface quarries.
Inker cement, laterite blocks, phosphate rock, quartz sand, sand and gravel, crushed stones, sandstone, and salt; clay, gemstones, gold, iron ore, and limeare all mined in Cambodia.See website: Cambodia
Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)
Limestone is the primary mined product of Iowa.
