Limestone rock is a sedimentary rock which forms in the process of sedimentation at the bottom of lakes and oceans, or in caves. It is mainly composed of mineral calcite and aragonite, both of which are crystal forms of calcium carbonate. A limestone with 95 percent or more of calcium carbonate by weight is known as a high-calcium limestone. Its properties such as hardness,

Limestones are sedi-mentary rocks consisting principally of calcium carbonate (CaCO3). With an increase in magne- sium carbonate (MgCO3), limestone grades into dolomite or dolostone [CaMg(CO3)2]. Chalk is a type of very fine-grained limestone. Most lime-stones contain varying amounts of impurities in the form of sand, clay and iron-bearing materi-als. These impurities

Mine Safety Dust: Also known as "rock dust." Pulverized limestone is a white powder that can be sprayed onto exposed coal surfaces in an underground mine. This bright white coating improves illumination and reduces the amount of coal dust that becomes suspended in the air of the mine. This improves the air for breathing, and it also reduces the explosion hazard produced by particles of flammable coal dust
