Natural limestone contains silica in different proportions and is largely composed of calcite mineral. The limestone powder contains calcite mineral due to the marine organism. We have listed our name among the well established limestone manufacturers as well as one of the best limestone powder suppliers in India. The cost of limestone powder is quite affordable. Limestone often contains variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand as disseminations, nodules, or layers within the rock. The primary source of the calcite in limestone is most commonly marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze or alternatively are conglomerated in a coral reef (see lysocline for information on calcite dissolution). Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites and stalactites. Another form taken by calcite is that of oolites (oolitic limestone) which can be recognized by its granular appearance. Limestone makes up about 10% of the total volume of all sedimentary rocks. Limestones may also form in both lacustrine and evaporitedepositional environments. Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures. Karst topography and cave develop in carbonate rocks due to their solubility in dilute acidic groundwater. Cooling groundwater or mixing of different groundwaters will also create conditions suitable for cave formation. Coastal limestones are often eroded by organisms which bore into the rock by various means. This process is known as bioerosion. It is most common in the tropics, and it is known throughout the fossil record (see Taylor and Wilson, 2003). Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces. Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock. Folk and Dunham classifications are used to describe limestones more precisely. Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls and around hot or cold springs. Calcium carbonate is deposited where evaporation of the water leaves a solution that is supersaturated with chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls. Coquina is a poorly consolidated limestone composed of pieces of coral or shells. During regional metamorphism that occurs during the mountain building process (orogeny) limestone recrystallizes into marble. Limestone landscape Limestone is partially soluble, especially in acid and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. Limestone is therefore usually associated with hills and downland and occurs in regions with other sedimentary rocks, typically clays. Uses of limestone Limestone is very common in architecture, Limestone was also a very popular building block in the Middle Ages in the areas where it occurred since it is hard, durable, and commonly occurs in easily accessible surface exposures. Many medieval churches and castles in Europe are made of limestone. Beer stone was a popular kind of limestone for medieval buildings in southern England. Limestone and marble are very reactive to acid solutions, making acid rain a significant problem. Many limestone statues and building surfaces have suffered severe damage due to acid rain. Acid-based cleaning chemicals can also etch limestone, which should only be cleaned with a neutral or mild alkaline-based cleaner. Other uses include: The manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide); Cement and mortar; Pulverized limestone is used as a soil conditioner to neutralize acidic soil conditions; Crushed for use as aggregate�the solid base for many roads; Geological formations of limestone are among the best petroleum reservoirs; As a reagent in desulfurizations; Glass making, in some circumstances; Added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler. Toothpaste Suppression of methane explosions in underground coal mines Added to bread and cereals as a source of calcium.

Calcite minerals, Calcite is one of the commonest minerals, calcium carbonate, CaCO3, found in a great variety of crystalline forms: a major constituent of limestone, marble, and chalk; calc-spar.

We are offering limestone. natural limestone, it is typically formed over many years at the bottom of oceans or lakes from the accumulation of shells, bones and other calcium rich goods. The calcium in the bones & shells combines with carbon dioxide in theswater to boom calcium carbonate which is the basic mineral structure of all limestone. It are typically used for flooring, wall cladding, vanity tops etc. It is found in many varieties like limestone flooring & natural limestone and many more. In addition, we are the dominating limestone exporters from india.
