Dolomite for use as flux in steel metallurgy should be hard, compact and finegrained so that it can stand the burden of the batch in the blast furnace as well as the basic steel convertor. It should not be crystalline,, it should not have a saccharoidal texture which gives fritting effect in the furnace.

Since dolomite is a source of both of these minerals, don''t use it if you have serious kidney problems. Sarcoidosis : This condition increases the risk of absorbing too much calcium.
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth''s crust. Learn more about the structure, properties, and uses of dolomite in .
May 08, 2013· Dolomite is used as a slag former, slag modifier and as a refractory material. The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such as silica (SiO2), Alumina (Al2O3) along with sulphur (S) and Phosphorus (P).
Dolomite uses in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil ...
Dolomite is a white mediumvalue and economic type of sedimentary stone that forms entire layers. It is also a flux stone, meaning it can be used in the production of pig iron and, it is magma safe, with an extremely high melting point of 16507 °U, in fact, the highest melting point of all common stones, barring raw adamantine (and, because it cannot be melted, slade 1).
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.

million crushed limestones used to make lime. million tons of crushed limestone or dolomite used for soil treatment. million crushed limestones consumed in steel (blast) furnaces as a flux to react and produce liquid slag. million tons of crushed stone used for sulfur dioxide removal.
Dolomite as a ceramicmaterial is a uniform calcium magnesium carbonate. In ceramic glazes it is used as a source of magnesia and calcia. Other than talc, dolomite is the principle source of MgOin high temperature raw glazes. ''Dolomite matte'' stonewareglazes, for example, are highly prized for their pleasant ''silky'' surface texture.
Properties of Dolomite. Dolomite is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. Limestone that contains some dolomite is known as dolomitic limestone. Uses Of Dolomite. Dolomite is chosen for many construction and building product applications due to its hardness and density. A few applications applications are:
Dolomite and dolomitic lime are used for their magnesia content. Fluorspar is a neutral flux often used as an additive in steel making slags to improve fluidity, but it has also been used in combination with lime as a primary slag in electroslag refining (Duckworth and Hoyle, 1969). ...
In industry, dolomite is an important source for magnesium and calcium metals, and is used as a flux for metallurgy. A flux is a material that melts easily and can be used to remove impurities from metal ores or to make the slag produced by metal ore smelting more fluid so it can be disposed of more easily.
what used for dolomite in furnaces It is also used as flux. Bessemer converters and steel ladles are made using this stone. This stone is used as a flux material in blast furnaces, as a ramming equipment, and as a fettling material in open earth furnaces and soaking pits. Dolomite is also used in the production of mineral ...
Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore palletisation and as a flux .
Limestone, dolomite, chalk and marble can be turned into flux. Recipe is hammer + cobble: v2 Build 7: Flux will now be used when welding: v2 Build 15: Fluxes should again use the correct rock types: v2 Build 17: Borax can now be used as a flux. It yields 6 flux. v2 Build 26

Magnesium carbonate: flux for highfire range, increases glaze adhesion and viscosity. Used for matte glazes. Talc: Used as a flux in lowtemperature clay bodies, and as a flux in both low and highfire glazes. Dolomite: A calciummagnesium carbonate flux used .
The breakdown of reported specified dolomite national consumption was similar to that of limestone; 87% of consumption was used as a construction aggregate, 9% was used in chemical and metallurgical applications, and 3% was used for agricultural use (USGS 2007). 2.
By heating the mineral dolomite (CaMg(CO 3) 2). Uses: In steelmaking, both quicklime and calcined dolomite are used as a flux and slag conditioner and to prevent the steel from oxidising. This process also collects impurities that are damaging to the steel. Calcined dolomite also protects the refractory lining of the steel furnace, oxygen ...
In agriculture, dolomite acts as suitable soil conditioner and ph controller. As reliable source of magnesia, this powder is used as food grade additive for livestock. In metal processing filed, it serves as a flux and sintering factor. In iron steel manufacturing arena, this powder is used for its excellent purification attributes.
While this article focuses mainly on the aggregate usage of the rock, many other vocations make use of the material. Some of Dolomite''s other uses include; acid neutralization, stream restoration, magnesia feed additives for livestock, use in pharmaceuticals, sintering agent and flux in metal processing, an ingredient in glass, brick, and ...
Dolomite is used as an ornamental stone, a concrete aggregate, and a Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.
