use of limestone and dolomite in iron ore pellet. Jun 10 2013 · Agglomeration of Iron Ore – Iron Ore Plant The purpose of agglomerating iron ore is to improve the permeability of blast furnace are commonly producedused in the industry namely Sinter and Pellet iron ore normally –3mm mixed with coke breeze 3mm limestone .
Standard pellets require less processing, are generally the least costly pellets to produce and are called "standard" because no ground fluxstone, such as limestone or dolomite, is added to the iron ore concentrate before turning the concentrate into pellets.
"Iron ore is also exported in a value-added, pelletized form. Full exemption from export duty is being provided to iron ore pellets to encourage the value addition process for fines". • Further, in the Budget Speech of subsequent year (2012 -13 at sl. No. 191), he also stated:
Mar 21, 2015· Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process.
The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets.
May 08, 2013· Iron and steel making. Basically limestone is used as a slag former. 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).
Jun 10, 2013· Most of the world's iron is made in blast furnaces, which produce liquid iron. . Iron ore pellets contain slagforming components, and are fed directly to the blast furnace. Iron ore fines are mixed at the ironworks with limestone, olivine, dolomite etc.
variable mixture of iron ores, limestone, olivine, bentonite, dolomite and miscellaneous iron‐bearing materials in the temperature range 1250 to 1350°C. The iron ore pellets are used principally as a
Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent.
In order to produce high-quality pellets, certain additives are important. The most common fluxing materials for iron ore pellet production are limestone (CaCO3), dolomite (Ca,Mg (CO3) 2) and olivine (Mg2 SiO 4), but sometimes magnesite (MgCO3) is also used.
Indurate briquettes, dolomite addition to iron ore, models of reduction. —————————— —————————— 1. Introduction Dolomite is an anhydrous carbonate mineral composed of Calcium Magnesium Carbonate, ideally CaMg(Co. 3) 2. The word dolomite is also used to describe the sedimentary rock, which composed ...
From the thickener, the mixture of high grade iron-ore and water is pumped into concentrate slurry storage tanks. To produce fluxed pellets, a mixture of limestone and dolomite is also ground to a very fine size and added to the concentrate slurry tank at the desired rate.
The flux pellets mix limestone and dolomite with iron at the front end of the process, instead of at the steel mill, Korpela said, saving the steelmaker time, energy and money. "They like us to ...
purpose of limestone in iron ore pellets Mine Equipments. Iron and Steel iea-etsap requires iron, steel scrap and lime (burnt limestone).The iron ore is smelted to produce an impure metal called "hot metal" when in liquid phase or "pig lump ore has a majority of particles with a diameter of > 4.75 mm; iron pellets are a by inert gas.
Iron ore pelletizing systems. Iron Ore Pellets are formed from beneficiated or run of mine iron fin The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as
effect of limestone binder in iron ore pellets Iron ore pellet raw material consists of a main ingredient iron sand, activated carbon, limestone, and a binder bentonite, drops, feces. Furthermore, raw iron ore pellets furnaces require physical pellet impact strength and high porosity because small particles can .
Dolomitic 'burnt' lime was found to be a suitable additive for the preparation of self-fluxed iron oxide pellets. The mechanical and metallurgical properties of the dolomitic lime pellets (B = 1.55) were generally superior to the regular pellets.
3rd COREM Symposium on Iron Ore Pelletizing Sept. 29 – Oct. 2, 2013 Quebec City . ... pellets, lump ore key physical properties are size consist, mechanical strength: ... such as limestone or dolomite in pelletizing, or oxide coatings after the pelletizing process.
Iron Ore Pelletizing Process An Overview. process. Additives such as limestone dolomite and hydrated lime are used to modify the chemical composition of the pellets Typical pellet plant using disc pelletizer as balling technology.

variable mixture of iron ores, limestone, olivine, bentonite, dolomite and miscellaneous iron‐bearing materials in the temperature range 1250 to 1350°C.
The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ore, limestone, olivine, bentonite, dolomite and miscellaneous iron bearing materials in the range of 1250 deg c to 1350 deg c.Iron ore pellets are normally produced in two types of grades namely dri grade and bf grade.
Pelletized Dolomitic Limestone is finely ground pulverized limestone with an organic binder to form a pellet. Limestone is a natural mineral which neutralizes acid and toxic elements, improves soil structure, promotes healthy bacteria and enhances nutrient availability and disease resistance.
