Quicklime called Calcium Oxide is created to discharge carbon dioxide through calcinating calcium carbonate (limestone). Quicklime is also called handpicked lime, burnt lime, lump lime, calcining lime, and caustic lime. It is an acidic material; by burning calcium carbonate limestone at approximately 900 degrees celsius, carbon dioxide is placed at this high temperature, and the limestone is converted into Quicklime. After heating, the quicklime is crumbled and then milled to the suitable fraction. We NBN Minerals are one of the significant best quicklime powder supplier in india and are known for their quality and services. It is a whitish, odourless alkaline substance with the chemical formula CaO. It can be stated that this compound does not dissolve well in water. The primary usage is in various industrial processes such as metal smelting, paper bleaching, sugar sulphur neutralisation, among many others.

It is crucial to the steel industry due to its practical use in the basic oxygen steelmaking (BOS) process. The service ranges from about 30 to 50kg per tonne of steel. Quicklime helps to neutralise acidic oxides, such as aluminium oxide and iron (III) oxide, to produce a basic molten slag.
Quicklime is a food additive with numerous objectives. It is widespread in the food industry as an acid regulator, a flour treatment agent and a leavener mattress maker.
In the construction industry, it is used to produce aerated concrete blocks, with densities of 0.6-1.0g/cm3.
Quicklime is essential to sugar production from both sugar cane and sugar beets. It is also used to refine sugar from different sources, such as maple or sorghum, although produced in much smaller quantities. Formation of raw juice with low pH, Sugar cane and sugar beets are harvested and processed with water and dissolved contaminants. Hydrated lime is added to the liquid to raise the pH and to react with the impurities to form insoluble calcium organic compounds that can be removed. Extra lime is removed by carbonation or by the accumulation of phosphoric acid. This procedure may be reprised several times, leaning on the purity of the final product required.
Lime water is frequently added to reduce acidity before pasteurisation when the cream is separated from whole milk during butter production. The skimmed milk is next acidified to isolate casein. The casein is blended with lime and a short amount of sodium fluoride to create calcium caseinate glue. Fermentation of the remaining skimmed milk (whey) and the addition of lime forms calcium lactate, which is marketed as a medicinal or acidification to produce lactic acid.
Waste materials from rendering plants are treated with lime in slurry form. This method swells the collagen, thereby facilitating subsequent hydrolysis. Afterwards, the treated stock is washed to remove lime, albumin, and mucin. The cleaned stock is dried, and the final product is sold as glue or gelatin.
