Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
For the commercial production of iron ore pellets from hematite ores, as it is practiced in various pellet plants, the addition of lime has shown to be an efficient means with a view to improving cold compression and abrasive strength of the indurated pellets considerably.
ore pellets [3]. Wynnyckyj and Fahidy [1974] found that the strength index of iron oxide pellet s is directly proportion with the shrinkage that takes place during burning of these pellets andthe addition of lime increases pellet shrinkage and hence increases pellet strength. They attributed this .
furnaces. It has direct influence on improving productivity and lowering energy consumption in iron making process. The reducibility of iron ore pellets of a specific chemistry can be improved by the optimization of physical parameters such as induration temperature, improving size distribution of fines, improving apparent porosity etc.

IMPACT YOUR PROFITABILITY Read case studies Read white papers Profitability Solutions: Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO2 emissions.
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
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 ...

Abstract. The effect of lime addition in hematite iron ore pelletson its physico-chemical as well as mechanical properties with respect to blast furnace requirement was studied in a laboratory scale with varying basicity i.e. 0-2.0.Increasing addition lime produced more calcium-alumino-silicate phases (slag)asevidenced by SEM-EDAX analysis.
Review of Organic Binders for Iron Ore Agglomeration J.A. Halt, S. Komar Kawatra . Department of Chemical Engineering . Michigan Technological University . Houghton, MI 49931 ©[email protected] . Date Last Edited: 5/22/2013 . Introduction Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making.
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 19, 2015· A laboratory study was carried out to characterize the physical, chemical and mechanical properties of lime fluxed (varying basicity 0–2) hematite iron ore pellets. Lime was used as additive as well as fluxing agent for making iron ore pellets. The effect of additives on different properties of pellets .
Feb 27, 2013· Dried limestone pellets should not exceed 5% attrition loss. An average of 2 – 3% loss is most common. ... Limestone Making Machine,Buy Quality Limestone Making . Limestone/lime pellet making machine. Min. Order: 1 Unit FOB Price: US $11111-111111 / Unit Supply Ability: 1 Unit/Units per Day. ... Iron ore pellets are spheres of typically 8 ...
Data on the influence of alumina and silica are therefore primarily of interest for assessing the likely effects of uncontrollable changes in the gangue content of iron ore used as pellet plant feed. Lime and Blaine index are variables which can be controlled at the feed preparation stage of a pellet plant. Lime is normally added as calcium ...
Jan 15, 2019· High MgO content and the dehydroxylation of laterite ore particles lead to poor compressive strength of fired chromium-nickel bearing iron ore pellets at natural basicity. For improving the compressive strength of the fired chromium‑nickel bearing iron ore pellets, burnt lime was applied as the additive to improve the pellet structure.
