Any iron ore beneficiation process primarily is governed by grinding, gravity separation, and filtration processes. The purpose of filtration is either clarification of liquids or solids recovery. In clarification the liquid is typically the valuable product and the solids are of minor quantity and are often discarded without any further treatment.

Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump ( mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.

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).
