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.

GENERAL INFORMATION
Quicklime or Calcium Oxide (CaO) is produced by heating Calcium Carbonate (e.g., limestone) in a special limekiln to about 1050�°C, decomposing it into Calcium Oxide and Carbon Dioxide. Our Quicklime product is sold in several sizes
Description
Industrial Raw Quicklime Mineral also known as calcium oxide CaO is a term commonly applied to several related materials. Pure lime is calcium oxide CaO formed by burning a form of calcium carbonate such as limestone or marble CaCO3. Calcium oxide is a key ingredient for the process of making cement. As a cheap and widely available alkali. About 50% of the total quicklime production is converted to calcium hydroxide before use. Both quick- and hydrated lime are used in the treatment of drinking water. Quicklime is used as Industrial Raw Materials with other industrial raw material products such as Silica Flour, Limestone, Aggregate, Talc, Volcanic Rock, Abrasives and Calcium Carbonate.
The quicklime products are often ground into a fine powder referred to as PULVERIZED QUICKLIME that is ideal for mixing with additives or other materials to result in specialized blended composites. Due to the chemical nature of some additives, the quicklime can become Fluidized, that is, having properties of being highly fluid. The fluidized quicklime is ideal for use with special material handling systems for optimum flowability and to avoid clogging. Quicklime can also be hydrated with water, in a process commonly referred to as slaking, resulting in HYDRATED QUICKLIME (or calcium hydroxide), a dry free-flowing powder product that is practical and efficient for many uses.
The relationship of quicklime and hydrated lime The word lime is also used to refer to calcium hydroxide and its chemical formula is Ca (OH) 2, and it is formed by the reaction of calcium oxide also with water. Calcium hydroxide is also known as hydrated lime, or hydrogenated lime while calcium oxide is known as quicklime. Both articles are rules.
There are a wide variety of uses for hydrated lime. It uses an auxiliary material for smelting in the production of iron. It is also used to purify aluminum, copper, and zinc, and remove the hardness of water by removing certain minerals from them. It also plays an important role in wastewater treatment. And we find many farmers spread lime in their fields to neutralize soil acidity. Homeowners also use it in their gardens to prevent algae growth. Lime helps hold soil in foundations of roads and runways. In the leather industry, it is used in tanneries to remove hair from animal hides. The mortar that is placed between the tiles or stones in the walls of buildings consists of a mixture of lime, sand, and water. It is also one of the most important components of gypsum, and one of the most important components of a type of cement called Portland cement.
