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.

The process is called calcination or lime-burning. This mined from the Wikipedia article on calcium oxide. A link is provided.
This past week I visited a limestone quarry that has been mining limestone in one place for 40 years. In that time, they will have mined millions of tons of limestone. Usually nearly ALL the rock is limestone, so the answer will depend on the size (area) of the quarry, how deep you can mine, and presence of any "trash" rock.
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 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)
