Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smeltingof iron and steel. Large quantities of processed dolo
The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, & Ohtsuka, 2010). The chemical composition of dolomite varies from source to source, but it generally contains 30 wt.% CaO, 21 wt.% MgO, and 45 wt.% CO 2. Dolomite also contains the trace minerals SiO 2, Fe 2 O 3, and Al 2 O 3.
4/22/2019· It also contains a small amount of impurities such as SiO 2, AlO 3 and FeO 3. The CaO/MgO ratio of natural dolomite fluctuates greatly. If the CaO/MgO ratio of brick is less than 1.39, it is called magnesia dolomite brick. In China, converter lining mainly uses tar-bonded dolomite bricks and tar-bonded magnesia dolomite bricks.

6/28/2017· Hence generally the rock containing in the range of 40 % to 45 % of MgCO3 is usually called dolomite. The main uses of dolomite in iron and steel industry are (i) as a fluxing material (ii) for protection of refractory lining, and (iii) as a refractory raw material. Dolomite in iron and steel industry is normally used in three forms.
Dolomite is also used in some cement, pharmaceutical, fodder, Glass and ceramic industry as a source of magnesium As a sintering agent in iron ore pelletization or as a flux agents in steel making. In agriculture, dolomite uses serves as pH control, while the chemical industry uses the mineral in making magnesium salts
Application : Chemical Industry Dolomite Powder is the Limestone Powder with Composition of Caco3 and Mgco3 Pertaining to 100% in Combination, the Proportion Being Varied as per Mining Zone. Dolomite is also Being Used as Fillers By Detergents, Steel, Paints and Ceramics.
There are also many uses for dolomite as a neutralizer in the chemical industry, or as a source of MgO, for nutrients or for the production of ceramics and glass, among other application (Perera
It is used for acid neutralization in the chemical industry, in stream restoration projects, and as a soil conditioner. Dolomite is used as a source of magnesia (MgO), a feed additive for livestock, a sintering agent and flux in metal processing, and as an ingredient in the production of glass, bricks, and ceramics.
Dolomite Uses In Chemical Industry. dolomite uses in chemical industry china uses of dolomite in china dapepponenl Chemical industry in China China's production of steel increased from 100 million tons in 2000 to 250 million tons in 2004 It caused rising demand for raw materials which is necessary for steel production, included pig iron, iron ore, scrap metal, lime and dolomite, coke and coal The
Uses. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces.

Dolomite is a double carbonate of calcium and magnesium (CaC03, MgC03). It is one of the important raw material used in iron & steel, ferroalloys, glass, alloy steels, fertilizer industry etc. Dolomite chips are also used in flooring tiles. 1.
Going forward, dolomite will be increasingly used in the cement industry for manufacturing cement and asphalt aggregates. While market players are exploring potential opportunities in other industries glass & ceramics, and agrochemicals the mining & metallurgy industry would
5/8/2013· For many of the applications in the iron and steel industry there are strict limits on the chemistry of the dolomite used, which mainly needs to be low in SiO2 (frequently less than 1 % or even less than 0.55 %) in addition to low in S (less than 0.1 %) and P (less than 0.02 %).
Iron and Steel Industry : Dolomite is used in iron and steel industry as refractory raw materials and a flux. Ferro Manganese : Contains MgO 19 to 20%, C a O 28 to 30%, SiO 2 2 to 5% and R 2 O 3 2 to 2.5%. Glass : For certain commercial glass, the Fe 2 O 3 content up to 0.25% is permissible.
