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.
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.
Limestone has a diversified use in today's Industrial world. As a raw material it is used in the following industries and construction projects
Glass Industry:
Limestone is used in the purification of molten glass. Most glass is made by fusing a mixture of silica sand and soda ash, limestone dolomite and other material. Generally very high purity (CaCO3 98.5 % or CaO 55.2) is required for this application.
Iron Industry:
Limestone is used to remove impurities from molten iron. Limestone or lime is used as a flux to assist melting. The lime reacts with silica and alumina impurities in the ore and forms a slag which floats on the surface of the Melt
Steel Industry:
Limestone is also used as a flux in the steel industry and is required to remove silica and phosphorus from pig iron. The limestone required should be of high purity with low silica (5 to 2%) and sulphur of less than 0.1%.
