Calcium is a very reactive metal and is always found in a reacted state in compounds where it is ionic, present as the Ca2+ ion. The best known mineral is limestone, calcium carbonate. Calcium metal is not produced commercially in great quantities, one method of production is to react calcium oxide with aluminium at high temperature,
, a so-called aluminothermic reaction similar to the thermite reaction where aluminium is the reducing agent.

How is lime mined?
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)
