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 high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

These operations imply high energy consumption. Thus, the amount of energy required to produce an iron ore grinded product, suitable for sale as pellet or sinter plant feed is substantially more than an equivalent lump (>16 mm) project (McNab et al., 2009). Besides energy, other costs impact the grinding and concentration of lumps, such as …
