Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the

The flat-lying fossiliferous limestone unit is approximately 30 m thick. Overburden comprises 3–4 m of calcrete, the lower 2 m of which is high in clay, which also infills solution cavities and pipes extending up to 20 m below the surface. The limestone is extracted by ripping and dozing, although some blasting of hard bands is required.

Graphite Mining. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.

Limestone mining can pollute water and create sinkholes. When limestone dissolves while it’s still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn’t hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.
