Dolomite Dolomite 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. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded ...
No, Limstone is not an ore but magnetite, hematite, kimbertite, and bauxite are so examples of or...
The Global Minerals Group scans the world mineral map and identifies assets in steelmaking raw material iron ore, coal, limestone, etc. We follow a systemic review of geology and resource base and business inputs to look for opportunities that are beneficial to and in .
It is also added to the mixes that are used to manufacture a wide variety of concrete products such as pipes and blocks. Our dolomitic limestone is also used by farmers to enhance the productivity of their fields, and as a feedstock to manufacture fluxed iron ore pellets and various glass products.
May 08, 2013· basic, dolomite, flux, limestone, neutraliziing, slag, Limestone and dolomite flux and their use in iron and steel plant. Limestone is a naturally occurring mineral. The term limestone is applied to any calcareous sedimentary rock consisting essentially of carbonates. The ore is widely available geographically all over the world.
Mar 05, 2018· LimestoneLimestone undergoes calcination to form calcined lime in furnace lime reduces the liquidus temperature of impurities in raw material added in blast furnace thereby helps in easy removal of impurities in form of slag ...
Missouri also used to be a leader in iron ore production. Most recently, the Pea Ridge Mine in Washington County was the deepest working iron ore mine in the Missouri had many iron ore mines operating the southeastern part of the state. Dr.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its ironcontent.
The first process takes place at dolomite mines where the mined ore undergo crushing and screening for the separation of the different size fractions of the ore. In the iron and steel plant, in some of the places, raw dolomite is further processed.

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Limestone vs Dolomite information and Limestone vs ...
Woodward Iron Company Four ironmaking enterprises, each controlling substantial deposits of iron ore, coal, limestone and dolomite, came to dominate the industry. These companies were unique in their use of advanced blastfurnace plants that smelted iron ore into pig iron. Woodward Iron, Sloss Sheffield Steel and Iron Company, and Thomas Works operated blastfurnace plants that produced .
The chunk of the iron ore is exported to be used in steel manufacture and pig iron and sponge iron plants. Limestone: It is another important mineral with an estimated 51,000 million tons. Karnataka has the largest limestone reserve in India. The districts of Gulbarga, Bagalkot, Belgaum, Shimoga and other Uttara Kannada districts are endowed ...

Nov 13, 2017· limestone is used to remove impurities in the furnace and the main impurity of the blast furnace is silica (sand and rock) which is silicon dioxide. silicon dioxide is a solid at furnace temperatures so it reacts with calcium oxide from the decomp...
In sedimentary dolostones, dolomite is most often associated with calcite, aragonite, gypsum, anhydrite, chert, and halite. Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite.
Dolomite can also serve as a host rock for lead, zinc, and copper deposits. In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel.
In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. The raw material grain size affects the sinter process considerably because the sinter productivity and quality are strongly dependent on the green permeability of ...

Properties of rock is another aspect for Dolomite vs Limestone. The hardness of Dolomite is and that of Limestone is 34. The types of Dolomite are Boninite and Jasperoid whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone.
Other uses of dolomite are in the chemical industry used to extract magnesia where it is served as the source rock. Steel industry use it in processing iron ore and is also used in the agriculture industry as a feed additive for live stock aiding in the egg shells which are made of calcium. It is also used in the production of glass and ceramics.

Aug 01, 2016· Silica and alumina contents in dolomite are not regarded deleterious for blast furnaces. They only cause unnecessary increase in the slag. Dolomite has been found as a useful support to limestone in removing sulphur from the iron ore. It also reduces the viscosity of the slag, thus chemical reactions in the furnace.
