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).

Cliff's Tilden plant in Cleveland, USA, is the only iron ore beneficiation plant, where selective flocculation technique, using degraded starch as the flocculant, has been applied to produce pellet grade concentrate from a feed containing around 32% Fe . The plant has a capacity of processing 10 million tons and is in operation since 1975.
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 lowgrade 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 ...

The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives —anthracite, dolomite —and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process;
Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a highquality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use.
Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
The configuration of iron ore powder in the blast furnace is more tightly packed and restricts the air flow. This is the reason that iron ore is preferred in form of pellets rather than in form of finer particles. Iron ore fines are generated by crushing and grinding lump ore.
