Iron Ore: Techno-economical Issues
The country’s iron ore requirement is going to increase substantially
(almost 340 Mt/yr by 2020)
The ration of Lump to Fines produced is 2:3
The percentage of Fines to lumps is generally rising as mining goes deeper
Fines generated as such cannot be used for Iron Making (BF/DRI)
Large portion of the Fines are being exported
Limited reserves of high grade iron ore (+62% Fe) pose a great challenge in
long term sustainability of Indian iron & steel industry
There is a pressing need to utilize existing low grade iron ores including
slimes and dump fines which are stockpiled in millions of tonnes in different
mine heads
The availability of large quantities of subgrade fines and slimes in the
mines has necessitated beneficiation of the same followed by
pelletisation.
Beneficiation of low grade ores, mostly at micro-fines level, provides
concentrate which can be used in iron making in the form of pellets
8
Agglomeration of Iron Ore Fines
Agglomeration of Iron Ore Fines basically involves two main methods
1. Sintering
2. Pelletising
Sintering is the agglomeration technique of Iron Ore Fines in the size rage of 10+0.15 mm to produce clusters by incipient fusion at high temperature.
Pelletisation is the other mode of agglomeration applicable for fines below 325
mesh size.
1% replacement of calibrated lump by Sinter or Pellet reduces the Coke rate by
1.5Kg/T of hot metal produced
20 to 70% Sinter can be used successfully in Blast Furnace
Use of Pellet gives rise to improved permeability compared to Lump Ore or Sinter
15 to 20% of pellets are used in many furnaces along with lump ore & sinter

Ore Beneficiation, Pellet Plants
and Sinter Plant
Ore Beneficiation & Pellet Plants
Ore Beneficiation
Very low grade Iron ore cannot be used in metallurgical plants
Needs to be upgraded to increase the iron content and reduce the gangue
content
.
.
A process adopted to upgrade ore is called Beneficiation
Each source of Iron ore has its own peculiar mineralogical characteristics
Specific beneficiation and metallurgical treatment to get the best product
out of it
Several techniques such as washing, jigging, magnetic separation, advanced
gravity separation and flotation are being employed to enhance the quality of
the Iron ore
Major Equipment
Ball mills for primary grinding and
regrinding
Concentrate, tails & hydro-cyclone overflow Thickeners
Hydro-cyclones for classification and desliming
Slime Tanks with agitators & Sumps
Wet high intensity magnetic separator
Agglomeration (Sintering & Pelletising)
•
•
Common methods of burden preparation related to the performance
improvements of iron making (blast furnaces & direct reduction process)
Growth of steel industry with depleting resources of high grade ores have led to a
very strong demand for both pelletising and sintering of iron ores.
Pellet Plant
The process of Pelletisation helps converting Iron Ore Fines into
“Uniform Size Iron Ore Pallets” that can be fed in the blast furnaces
or in the DRI kiln (DRI).
Pelletisation was invented to make use of ultra fine concentrate
generated in the Iron ore beneficiation plants
There are two main processes for producing iron ore pellets:
(1).The Grate-Kiln System
(2).The straight grate system
Major Equipment
Pulverizing mill for lime stone, bentonite
and coal
Travelling grate complete with burners,
lubricating system and accessories
Intensive Mixer with accessories
Rotary kiln with accessories
Swing Belt Conveyor & wide belt conveyor
Annular Cooler
Roller screen for screening green pellets
Pellet Plant-Grate-Kiln System
Process adopts three equipment viz. grate, rotary kiln and annular
cooler
Green balls are first dried and preheated on the straight grate followed
by hardening in a counter flow manner in rotary kiln and air cooling in an
annular cooler
Pellet Plant-Straight Grate System
In the straight grate system, a continuous parade of grate cars moves at
the same speed though the drying, induration and cooling zones.
Sinter Plant
Sinter making is a method of fusing iron ore fines into larger particles
suitable for charging into the blast furnace.
Major Equipment – Sinter Plant
Proportioning
Mixing & Nodulizing
Sintering
Sinter Cooler
Cold Sinter crushing
Cold Sinter screening
Waste Gas & Plant de-dusting

THANKS
Need for Pelletisation Contd.
ADVANTAGES OF PELLETS:
• Good Reducibility:
Because of their high porosity that is (25-30%), pellets are usually reduced
considerably faster than hard burden sinter or hard natural ores/lump ores.
• Good Bed Permeability:
Their spherical shapes and containing open pores, gives them good bed
permeability. Low angle of repose however is a drawback for pellet and creates
uneven binder distribution.
• High uniform Porosity (25-30%):
Because of high uniform porosity of pellets, faster reduction and high metallization
takes place.
• Less heat consumption than sintering.
Approx. 35-40% less heat required than sintering.
• Uniform chemical composition & very low LOI:
The chemical analysis is to a degree controllable in the concentration processing
within limits dictated by economics. In reality no LOI makes them cost effective.
• Easy handling and transportation.
Unlike Sinter, pellets have high strength and can be transported to long distances
without fine generation. It has also good resistance to disintegration.

The three different methods that can be used for production of iron
from Iron ore are:
• Coke-Ovens -Sinter-Blast Furnace (BF) Route
• Direct Reduction Technique (DRI)
• Smelting Reduction Technologies.
For producing Crude Steel, two types of techniques are adopted;
• Basic Oxygen Furnace (BOF) type
