Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities silicon dioxide to form a slag.
Pelletized lime is finely ground up limestone, according to the University of Kentucky. It is used to raise the soil s pH or make the soil more alkaline for grass growth. The optimal pH for grass is between 6.0 and 7.0. The best time to apply limestone depends on if you want to seed your lawn and the time of year.

Both processes can be used to generate almost any type of desired pellet chemistry, from direct reduction pellets DR pellets to blast furnace pellets. By adjusting the amount of fluxing agent or limestone added, pellets can be made that are anywhere from acid or non fluxed pellets to heavily fluxed pellets.
Jan 01, 2012 0183 32 The use of hydrated lime as a binder is most attractive when fluxed pellets are being produced, which require several percent CaO and or MgO to be added to the pellet. In traditional fluxed pellets, the flux is added as limestone CaCO 3 or dolomite CaMg CO 3 2 , neither of which has any appreciable binding properties.

why limestone used in pelletising of iron nvsiprint. An In Depth Analysis of Limestone Pelletizing. Pelletized limestone is commonly used as a soil additive for agricultural purposes.
Iron ores are usually purchased as fines or as pellets consisting mostly of iron oxide. Iron ore pellets are fed directly into the blast furnace. Iron ore fines are mixed at the ironworks with limestone and other minerals and pre fired at low temperatures to form a sinter, i.e. agglomerates that can then be
Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Our limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.
Aug 10, 2015 0183 32 Acid iron ore pellets with 4.6 wt. SiO 2 manufactured by Severstal Resources in Karelia were used in the investigations. Both test pellets were produced in a laboratory scale pelletizing drum and fired in sample baskets set in the middle of the sintering belt on the same production line as commercial blast furnace pellets.
