Introduction
Iron ore is a ferrous metallic mineral used for many industrial, commercial and household uses. Ferrous minerals account for about three fourths of the total value of the production of metallic minerals. They provide a strong base for the development of metallurgical industries. India exports substantial quantities of ferrous minerals after meeting her internal demands.

About Iron Ore
01
Did you know?
Iron makes up close to 5% of the Earth's crust.
It takes around 1.6 tons of iron ore to produce one ton of steel.
The world uses 20 times more iron (in the form of steel) than all other metals put together.
Our iron ore trains are over 2.5km, or 264 ore cars long! It can take up to half an hour to walk from one end to the other.
The ships we use to transport iron ore to our customers can carry around 47 Olympic-sized swimming pools worth of material.
The chemical symbol for iron is 'Fe'. This comes from its Latin name, Ferrum.
Iron Ore
Iron ore is the basic mineral and the backbone of industrial development.
India is endowed with fairly abundant resources of iron ore. India is rich in good quality iron ores.
In 2018–19 almost entire production of iron ore (97%) accrued from Odisha, Chhattisgarh, Karnataka and Jharkhand. The remaining production (3%) was from other states.
Magnetite
02
Magnetite
Magnetite is the finest iron ore with a very high content of iron up to 70 per cent.
It has excellent magnetic qualities, especially valuable in the electrical industry.
Hematite
03
Hematite
Hematite ore is the most important industrial iron ore in terms of the quantity used.
Hematite was once used as mourning jewelry. A 1923 reference describes "hematite is sometimes used as settings in mourning jewelry."
It has a slightly lower iron content than magnetite(50-60 per cent).
The formula for hematite is 𝑭_(𝒆_𝟐 ) 𝑶_𝟑 and the chemical name is iron(III) oxide.

3. Introduction
Iron ore is a ferrous metallic mineral used for many
industrial, commercial and household uses. Ferrous
minerals account for about three fourths of the total
value of the production of metallic minerals. They
provide a strong base for the development of
metallurgical industries. India exports substantial
quantities of ferrous minerals after meeting her
internal demands.

• Iron ore is the basic mineral and the
backbone of industrial development.
• India is endowed with fairly abundant
resources of iron ore. India is rich in good
quality iron ores.
• In 2018–19 almost entire production of iron
ore (97%) accrued from Odisha,
Chhattisgarh, Karnataka and Jharkhand. The
remaining production (3%) was from other
states.
9. Magnetite
Magnetite is the finest
iron ore with a very high
content of iron up to 70
per cent.
It has excellent
magnetic qualities,
especially valuable in the
electrical industry.
Magnetite is a mineral
whose primary
component is an iron
oxide that contains equal
amounts of iron(II) and
iron(III).
The formula for magnetite
is 𝑭𝒆𝟑𝑶𝟒 and the chemical
name is iron (II,III) oxide.
11. Hematite
Hematite ore is the
most important
industrial iron ore in
terms of the quantity
used.
Hematite was once used
as mourning jewelry. A
1923 reference describes
"hematite is sometimes
used as settings in
mourning jewelry."
It has a slightly
lower iron
content than
magnetite(50-60
per cent).
The formula for
hematite is 𝑭𝒆𝟐
𝑶𝟑
and the chemical
name is iron(III)
oxide.

Others
14. Odisha- Jharkhand belt
Ore Found: Hematite Ore
Location: Odisha – Badampahar mines
in the Mayurbhanj and Kendujhar
districts.
Jharkhand - Gua and Noamundi mines
in the Singbhum district.
15. Durg-Bastar-Chandrapur belt
Ore Found: High grade Hematite ore.
Location: Chhattisgarh – Bailadila Range of hills in
the Bastar district. (The range of hills comprise of
14 deposits of super high grade hematite iron ore).
Maharashtra.
Used for: Steel making
Exported Countries: Japan and South Korea via
Vishakhapatnam port.
16. Ballari-Chitradurga-
ChikkamagaluruTumakuru belt
Large reserves of iron ore.
Location: Karnataka - Kudremukh
mines located in the Western Ghats.
It is a 100 per cent export unit.
Kudremukh deposits are known to be
one of the largest in the world.
The ore is transported as slurry
through a pipeline to a port near
Mangaluru.
17. Maharashtra-Goa belt
Location: Goa and Maharashtra -
Ratnagiri district
Though, the ores are not of very high
quality, yet they are efficiently
exploited.
Exported through: Marmagao port.
