Effect of adding limestone on the metallurgical properties ...
In general, the main types of pellets for the purposes of making iron are acid, basic and fluxed. In order to produce high-quality pellets, certain additives are important. The most common fluxing materials for iron ore pellet production are limestone (CaCO 3), dolomite (Ca,Mg(CO 3) 2) and olivine (Mg 2 SiO 4), but sometimes magnesite (MgCO 3) is also used.

Pelletizing - Wikipedia
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the stone composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder. The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatm…

May 08, 2013 · 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).
Iron ore pellets – IspatGuru
Dec 28, 2013 · 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.
What is the purpose of limestone in a blast furnace? - Quora
Answered November 14, 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 decomposition of limestone (CaCO3). this result into the formation of calcium silicate (CaSiO3) or slag which is a liquid. slag flows …

How A Blast Furnace Works – twinkletwinklelittlestar
Apr 28, 2014 · Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content. Pellets are produced from this lower iron content ore. This ore is crushed and ground into a powder so the waste material called gangue can be removed. The remaining iron-rich powder is rolled into balls and fired in a furnace to produce strong, marble-sized pellets that contain 60% to 65% iron. …
