Abstract 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.
The Kudremukh plant in Karnataka was the first big iron ore beneficiation plant in India. It mainly processes complex haematite and magnetite ore. It got pelletisation facility for pellet making from the concentrate of beneficiation plant. Pellets are not for domestic consumption rather exported for revenue generation.
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.
Merchant DRgrade iron ore pellet demand may increase to 53 million mt in 2025 from about 38 million mt in 2020, and rise to 81 million mt in 2030, according to IIMA estimates. Around million mt of estimated marketbased DR pellet demand in 2030 is expected to come from new DR plants, mainly in Europe and the MENA region, at which time ...

The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Grinding. This is the second size reduction process in a pellet plant. In order to improve the wood pellet quality and output and lower the energy consumption of the pellet mill, we use a hammer mill to grind the raw materials into small particles with a diameter less than 5mm. The smaller the raw materials are, the better wood pellet we make.
