Limestone
300 - 1,200 Per MT
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris. Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. Lime also has major applications in the manufacture of glass and in agriculture.

Limestone is one of the oldest materials that are widely used by human beings for different applications. Presently, these products act as a necessary building block for all industrial process. We offer superior quality limestone , which are highly admired by all our clients. The limestone offered by us is manufactured from premium quality material and is free from any unwanted particle. Our genuine quality limestone are accessible at the least market prices. In addition to all this, we are among the preeminent limestone suppliers in India. We stand as one of the prominent Quartz mineral suppliers in India. We also offer quartz at various advantageous deals, which are highly admired by all our clients. Our exclusive range of quartz comprises of quartz powder and quartz stone, and quartz ramming mass. The quartz that we supply is extracted out of lattice of silica (SiO2) tetrahedra. The quartz mineral offered by us is 100% pure and free from any impurities. We strive to offer quartz mineral within the prescribed time period and that too at affordable prices. Quartz belongs to the rhombohedra crystal system. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned, distorted, or so inter grown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces altogether and appear massive. Well-formed crystals typically form in a 'bed' that has unconstrained growth into a void, but because the crystals must be attached at the other end to a matrix; only one termination pyramid is present. A quartz geode is such a situation where the void is approximately spherical in shape, lined with a bed of crystals pointing inward. Pure quartz is colorless or white colored varieties include rose quartz, amethyst, smoky quartz, milky quartz, and others. Quartz goes by an array of different names. The most important distinction between types of quartz is that of macro crystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification). Chalcedony is a generic term for cryptocrystalline quartz. The cryptocrystalline varieties are either translucent or mostly opaque, while the transparent varieties tend to be macro crystalline. Uses Of Lime Because of its strong basic properties, calcium hydroxide has many and varied uses: A flocculant, in water and sewage treatment and improvement of acid soilsAn ingredient in whitewash, mortar, and plasterAn alkali used as a lye substitute in no-lye hair relaxersA chemical depilatory agent found in NairAn ingredient in baby formula milkA chemical reagentIn the reef aquarium hobby for adding bio-available calcium in solution for calcium-using animals such as algae, snails, hard tube worms, and Corals (often referred to as Kalkwasser mix), and also to increase the alkalinity of the water.In the tanning industry for neutralization of acid, the liming of hides and skins and the flocculation of wastewater.In the petroleum refining industry for the manufacture of additives to oils (salicatic, sulphatic, fenatic)In the chemical industry for manufacture of calcium stearateIn the food industry for processing water (for alcoholic and soft drinks)For clearing a brine of carbonates of calcium and magnesium in the manufacture of salt for food and pharmacopoeiaIn Native American and Latin American cooking, calcium hydroxide is called "cal". Corn cooked with cal becomes nixtamal which significantly increases its nutrition value, and is also considered tastier and easier to digest.In chewing Betel nut or coca leaves, calcium hydroxide is usually chewed alongside to keep the alkaloid stimulants chemically available for absorption by the bodySimilarly, Native Americans traditionally chewed tobacco leaves with calcium hydroxide derived from burnt shells to enhance the effectsA fillerIn the petrochemical industry for manufacturing solid oil of various marksIn the manufacture of brake padsIn the manufacture of eboniteFor preparation of dry mixes for painting and decoratingIn manufacturing mixes for pesticidesIn manufacturing the trademarked compound "Polikar", an antifungal and antimicrobial preservative for vegetables in storageIn Dentistry, it is used as dressing in paste form used for anti-microbial effect during a dental root canal procedure. Calcium hydroxide is known to have a strong anti-microbial effect and is a bone-regeneration stimulant.It has been proposed to add it to sea water in great quantities to reduce atmospheric CO2 and fight the greenhouse effectUsed as an acid suppressor in the production of metals. Lime is injected into the waste gas stream to neutralize acids such as fluorides and chlorides prior to being released to atmosphere.
