The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium to highgrade (+62% Fe) and are directly used in blast furnace and in directreduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and SteelVision, 2020).

Abstract. In iron making process, sintering of iron ore fines is an integral step to utilize not only the ore fines but also to introduce a part of flux (limestone and dolomite) along with the sinter in blast furnace burden. In this way, the productivity of the furnace considerably improves. In this paper, some fundamental aspects such as the ...

Here, the outline and characteristics of iron ore deposits are discussed. A reasonable definition of iron ore would be "ore that enables economical production of iron and steel reflecting the steelmaking technology in each era" (Inazumi 2009).Even if an iron ore has excellent quality and properties, it is merely a stone unless iron and steel can be obtained affordably.

The iron ore deposits of Iron Quadrangle were subjected at least to two metamorphism and deformation events. The metamorphic and deformation intensity increase from west to east and from south to north in the region. These processes beyond the supergene processes were the main factors that changed the texture of the iron ore of this region.

The rule of LPF index of iron ores under the mole ratio method is different from that with basicity method. When the mole ratio method is used, the LPF index of iron ore decreases with the increase in gangue content. The molar ratio method is more in line with the liquid phase formation behavior of iron ore during the actual sintering process. 2.
