Limestone is a commonly sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Limestone constitutes approximately 10 percent of the sedimentary rocks on the earth’s surface.

Limestone is formed directly crystalise from water (usually seawater), or by the accumulation of sea animal shells. In the direct crystallization calcium ions in the seawater combine with atmospheric or dissolved carbon dioxide to form calcium carbonate, which being insoluble, precipitates out. layers of the calcium carbonate form and pressure from overlying materials, are transformed to solid rock. The chemical composition of seawater and its minerals contaminated will be recorded in the limestone impurities. Limeston also contains the minerals dolomite or calcium magnesium carbonate (CaMg(CO3)2.

At that time much of the earth in earlier geological lived many clams and other shelled forms of animal life. When the animals died, their shells, which are composed of calcium carbonate, fell to the bottom. Thick layers, which can be a mile or 2 kilometers deep, gradually were changed into rock. If the shells were only compressed, with little crystallization occurring, it results in soft chalk. The White Cliffs of Dover in England are made of this type of chalk.At high pressure, crystallized rock can form, which is called as limestone. In limestone, most of the animal shells have disappeared.

Pure calcite, dolomite which are in the limestones, are clear or white. if their is impurities, they can take a different variety of colors, commonly white or gray. Limestone can be gone through metamorphosis, with high pressure and heat. This process tends to identify the color of the stone as well as changing the nature of the impurities. Metamorphosis creates the beautiful marbles seen in architectural applications.

Uses For Limestone
Limestone and marble are important building materials all most parts of the world. They are using in cut dimension stone (blocks and slabs) for building. In the formation of crushed stone or aggregate limestone genarally used for building purposes. When limestone heated, the calcium carbonate in limestone decomposed to lime, or calcium oxide,it has many industrial applications, including the manufacturing of precipitated calcium carbonate (PCC).

Either limestone or marble may be used for the basis of crushed or ground calcium carbonate. Ground calcium carbonate, commonly referred to as GCC, is very widely used as an industrial mineral. Three primary attributes defined the quality of GCC: particle size, color and chemical purity.

Ground limestones are available in a broad range or sizes. When it specify the size of a ground calcium carbonate, either the top size (the size of the largest particles) or the medium, particle size (essentially the average) can be used. Commercially, top size is generally specified for industrial minerals, which is 10 mesh or 2 millimeters or approximately 0.1 inch in size, or as fine as flour; which is 200 mesh, or 75 microns. Finely ground calcium carbonates can be down in particle size to just a few microns, 1 to 3.

Limestone color has range from brilliant white to light gray and chemical purity has range only 80-90%.

Calcium carbonate is not a hard mineral,or pure calcite falling about 3 on the Mohs scale of 1 (talc) to 10 (diamond). Silica impurities in the limestone can be raised the hardness of some ground calcium carbonates to a Mohs value of 4. Calcium carbonate is being attack by acidic environments, which has led to the damage of limestone buildings and also caused acid rain. For industrial uses, the effect of an acid can be reduced by treating the ground limestone powder with fatty acids to put a non-polar, organic material on the surface. Few industrial minerals can match GCC for its combination of properties and cost.
