Calcined Dolomite is an element that plays an essential role in the steel sector, both for its purifying action and for the preservation of refractory linings. We are among the Best Calcined Dolomite Suppliers and Manufacturers in India.
Through the calcination process, Calcium and magnesium oxide or Calcined Dolomite are obtained from dolomitic minerals, such as calcium carbonate and magnesium (Ca Mg (CO3)2) .
The calcined Dolomite is received from the heating of the crude Dolomite in a horizontal oven.
Ca Mg (CO3)2 + Tª (800ºC) -> CaO MgO calcinado + 2CO2
Once the final product is fetched, it is categorised in diverse grain sizes, adapting to the necessities of each sector targeted.Calcined Dolomite is discovered in iron and steel industry applications, such as scorifiers and refractory lining protectors, agriculture as a soil conditioner, and in the environmental sector for water treatment.
Calcined Dolomite has also been utilised in metallurgy, chemistry, the manufacture of refractory bricks and stabilisation in the manufacture of glass, enhancing its resistance to the aggression of gases and humidity.

Micronized calcium carbonate is utilised as a food additive in animal feasts. For birds, a refinement in egg quality and shell hardness is acquired. Calcium soaps subsequently intended for the animal meal and used to qualify Calcium Oxide with very fine grading and high reactivity. Calcium soaps are manufactured by reacting with liquid fat and the water present with calcium oxide. As a result, the superior product is dry and fluffy.
NBN Minerals presents specific calcium-based products created for these sectors to improve energy, boost efficiency, and decrease manufacturing emissions. Calcium based products are some of the essential components in glass and ceramic formulations
There are integral parts in the ceramic sector in both the tile and the glaze that wraps it. Changing from clay into a durable and long-lasting compound can happen through heating. The mineral is subjected to firing that reacts with the silica and alumina.
NBN Minerals supply the products necessary for success in the steel and iron making process, such as Quicklime, Calcined Dolomite and refractory materials. Iron ore or scrap metal is the base of obtaining steel.
Calcined Dolomite is added in EAF and the refining ladle and acts a dual role. On the one hand, it experiences the removal of sulphur and phosphorus. On the other, it permeates the magnesium oxide in the slag, boosting the useful life of the refractory covering.
Quicklime or calcium hydroxide primps the Sludge, killing the microorganisms and bacteria present; in the same way, it stops their growth and reduces bad smells. Some industrial operations are developed through products in the form of Sludge, which needs to be managed appropriately.
A gigantic quantity of Sludge is generated in the filtration and decantation process in the water treatment sector. Relying on its origin, Sludge contains a high moisture percentage, making it tough to manage. Due to its organic load, bacteria develop foul odour.
Depending on the method used to extract minerals, the product
Flux, scorifier and tuner of alloy composition include Calcium based products. We also have refractory concrete for the aluminium smelting industry. Metallurgy confines a set of techniques to extract metals, such as copper, zinc, lead, silver, nickel, uranium, and gold, from the minerals that retain them, depending on the method used in each case.
NBN Minerals is wholly devoted to the Minerals & Metal Industry, and we are a premium quality manufacturer and supplier of Calcined Dolomite in India. Currently, we deal with Calcined Dolomite powder in bulk at reasonable prices. To get more information, get in touch now on https://www.nbnminerals.com/
