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.

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.
