Question

Write the names of any 2 iron-producing states of India.

Answer 1

Hint: India ranks fourth in the world in iron production producing 210,000 tonnes of iron. Australia, Brazil, China, India and Russia are the other largest producers.

Complete Step by Step Answer:
Haematite, Magnetite, Siderite, Iron pyrites are some of the ores of the Iron. Magnetite is the finest quality of iron ore, siderite being the cheap quality.

Magnetite comprises 70% of iron. Fe3O4 is the chemical formula of magnetite ore. Magnetite (Fe3O4) is reduced to Ferrous Oxide (FeO) and then later Iron is extracted from it. Largest producers of magnetite in India are Karnataka and Andhra Pradesh.

Hematite is the best quality of iron ore and has 70 per cent metallic content. It is found in Dharwad and Cuddapah of peninsular India. The major hematite producing states are Odisha, Jharkhand, Chhattisgarh and Andhra Pradesh.

Siderite is the inferior quality iron ore which has less than 40% of iron ore. It is self-fluxing due to the presence of lime.

Limonite is also an Inferior ore which contains 40 to 60 percent of iron metal. Duda series in Raniganj coalfield, Mirzapur in Uttar Pradesh and Kangra valley of Himachal Pradesh produce this type of ore. The advantage of this type of iron ore is that it is easy and cheap to mine.

The major iron ore belts in India are :
Odisha-Jharkhand belt
Durg-Bastar-Chandrapur belt, Chattisgarh
Bellary-Chitradurga-Chikmagalur-Tumkur belt, Karnataka
Maharashtra-Goa belt

Note: Around 99% per cent of India's iron ore is produced by five states of India, that is Karnataka, Orissa, Chhattisgarh, Goa and Jharkhand. Karnataka is the largest producer of Iron ore in India. It produces around 25% of the total iron produced in the country.
