Use of calcined dolomite as chemical coagulant in the simultaneous removal of nitrogen and phosphorus 6th International Conference on Sustainable Solid Waste Management PhD Janne Pesonen Research Unit of Sustainable Chemistry University of Oulu Finland. University of .
Before being used as alyst, the dolomite was ground on a cross beater mill Retsch SK 100 and sieved using a mesh 325 ASTM (<45 μm), thus obtaining the Natural Dolomite (ND). The Calcined Dolomite (CD) was obtained calcinating the ND at K during two hours in a .
· Calcined dolomite was also used to form sample S4 to further improve the photoalytic efficiency. Calcined dolomite was produced by calcination of raw dolomite (10 g) in a muffle furnace at the temperature of 600 °C for 25 min under atmospheric conditions. .
Calcined Dolomite Powder. We are among leading entities, engaged in offering supreme quality Calcined Dolomite Powder that occurs in igneous rocks as carbonate, in metamorphic rocks as marble and in hydrothermal deposits. Offered powder is used in processing of ornamental stone, road stone, and the production of refractory brick. Apart from this, this Calcined Dolomite Powder is appreciated ...
Synonyms which are also very commonly used in India: Burnt Dolomite, DoloLime, Calcined Dolomitic lime, steel grade dololime, steel grade dolomite. Burnt dolomite is a result of calcinations of natural dolomite lumps which contains 25% to 28% CaCO 3 and 15% to 18% MgCO 3. On calcination, calcium oxide contains becomes 50% to 55% and Magnesium ...
glassmaking and for agricultural use (Figure 1). Raw dolomite and calcined dolomite have a number of different uses in the iron and steel industry. However, changes in iron and steelmaking technology during the 20th century have had a marked effect on the demand for dolomite for specific uses and the market continues to evolve.
Calcined Dolomite Calcined dolomite is found in appliions in the iron and steel industry, such as in scorifiers and refractory lining protectors, in agriculture as a soil conditioner and in the environmental sector in water treatment, among others. Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide,
Calcined dolomite (CaO MgO), can also be used in water treatment plants, for example to eliminate silica from water. This is because the magnesium in the dolomite acts as the main reactive agent for the elimination of silica. The use of quicklime and slaked lime is much less common.
In this research, dolomite calcined at 650 °C, 750 °C, or 950 °C and commercial MgO were used as precipitants in simultaneous phosphate and ammonium removal from synthetic (NH4)2HPO4 solution and agricultural sludge. Calcination at 750 °C was the preferred option as dolomite was decomposed to MgO and CaCO3 for optimal struvite precipitation.
Dolomite is sometimes used both in the raw and calcined form as refractory material for hearth maintenance and for banking door in open hearth furnaces. For most refractory uses, it is desirable to subject the dolomite to a heat treatment at a high temperature of the order of 1700ºC, to shrink the material thoroughly and render it less reactive.
11/05/2020 · Calcined Dolomite: Dolomite can be calcined at 1000⁰C when the CO2 is completely driven off leaving a mixture of CaO and MgO. This calcined dolomite starts partially fusing at 1700 1800⁰C (a process called sintering) by which the magnesia is converted to periclase (the crystallized form of magnesia) and a dense inert product known as deadburnt dolomite or dolomais formed.

Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process. Ca Mg (CO3)2 + Heat [.]
· In this research, dolomite calcined at 650 °C, 750 °C, or 950 °C and commercial MgO were used as precipitants in simultaneous phosphate and ammonium removal from synthetic (NH4)2HPO4 solution ...
Uses of Dolomite. Dolomite and limestone are used in similar ways. They are crushed and used as an aggregate in construction projects. They are kilnfired in the manufacture of cement. They are cut into blocks and slabs for use as a dimension stone. They are calcined to produce lime. In some of these uses, dolomite is preferred.
