Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 ). Dolomite, CaMg (CO3)2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare.Major mineral deposits of the world Regional locations and general geologic setting of known deposits of major nonfuel mineral commodities. Download + details Global distribution of selected mines, deposits, and districts of critical mineralsLimestone is a sedimentary rock, although it has a hardness of 3-4 Mohs and a density of 2.5 to 2.7 grams per cubic centimeter. The rock is primarily composed of calcite or calcium carbonate, with most of these rocks being around 95% calcium carbonate. Being so high in calcium makes limestone rock polish and smooth better.Some deposits have chemical grades as high as 95% CaCO 3. However, some areas are completely without any suitable limestone deposits. Most of the cost of limestone to the customer is determined by how far away it comes from and how it is shipped. Shipping by barge on water is cheaper than by train which, in turn, is cheaper than shipping by truck.

Limestones consisting mainly of animal shells The shells of many aquatic animals consist of calcium carbonate (calcite and aragonite).Tufa. Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine.

Feb 5, 2016 · Limestone deposits are of sedimentary origin and exist in all the geological sequences from Pre-Cambrian to Recent except in Gondwana. 75 per cent Limestone is used in cement industry, 16 per cent in iron and steel industry [It acts as flux] and 4 per cent in the chemical industries. Rest of the limestone is used in paper, sugar, fertilizers, etc. The deposited limestone eventually forms stalactites and stalagmites. When groundwater-containing atmospheric CO 2 (Equations \(\ref{17.21}\) and \(\ref{17.22}\)) finds its way into microscopic cracks in the limestone deposits, CaCO 3 dissolves in the acidic solution in the reverse direction of Equation \(\ref{17.24}\). The cracks gradually ...The product of that reaction, calcium carbonate, is then deposited onto the ocean floor, where it becomes limestone. (Photograph ©2009 Greg Carley.)
