Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It often contains other minerals, such as clay, dolomite, and silic Appearance: Limestone can vary in color from white and gray to tan, brown, and even black. Its appearance can be influenced by impurities, organic materials, and the type of minerals present. Uses: Construction: Limestone is widely used as a building material for flooring, walls, and facades due to its durability and aesthetic appeal. Industry: It is used in various industries, such as cement production, where it serves as a key ingredient in the manufacturing of Portland cement. Agriculture: Limestone is used to improve soil quality by neutralizing acidity, providing essential nutrients like calcium, and promoting plant growth. Chemical Industry: It is used in the production of lime, which has applications in various chemical processes.
We produce limestone in different sizes as follows: * 6 - 15 mm * 15 - 25 mm * 25 - 50 mm * 50 - 150 mm * 0 - 40 mm * 0 - 50 mm * 40 - 80 mm
Quicklime (or calcium oxide or burnt lime) is obtained by calcining pure limestone at temperature above 9000C. This highly reactive product is essential to many industrial processes. Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. Application: Steel Making, FGD, Construction, Masonry & Mortars, Water Treatment, Chemical Processes, Mining Industry, sugar industry, Paper, Pulp and PCC, Remediation of Sludges and Wastes and Glass Manufacturing.

We have been manufacturer of limestone for over 20 years.
Limestone is a sedimentary rock which is often composed of the skeletal fragments of marine organisms such as coral, foraminifera and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the production of lime, as a soil conditioner, or as a popular decorative addition to rock gardens. To make Portland Cementâ??the most common type of Cementâ??powdered Limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.
Fine limestone available for export.

Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Limestone is a rock with an enormous diversity of uses. It could be the one rock that is used in more ways than any other. Most limestone is made into crushed stone and used as a construction material. It is used as a crushed stone for road base and railroad ballast. It is used as an aggregate in concrete. It is fired in a kiln with crushed shale to make cement. Some varieties of limestone perform well in these uses because they are strong, dense rocks with few pore spaces. These properties enable them to stand up well to abrasion and freeze-thaw. Although limestone does not perform as well in these uses as some of the harder silicate rocks, it is much easier to mine and does not exert the same level of wear on mining equipment, crushers, screens, and the beds of the vehicles that transport it.
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.
