Correct Answer: (a) Haematite
Solution:Haematite type of ores has the largest iron ore reserve in India. According to IMYB Report, 2021 the total resources/ Reserves of Haematite in the country is around 24057905 thousands tonnes as of 1 April, 2020. Iron ore is the most important metallic ore. It is known as the backbone of modern civilization. Many industries depend on iron, and hence it is also known as the fundamentals of all industries. Iron Ore is a naturally occurring solid material from which valuable minerals are extracted for commercial use. Iron ores are rocks and minerals that can be economically extracted to produce metallic iron. They are generally rich in iron oxides. They come in various colours such as dark grey, bright yellow, rusty red, deep purple, etc.
Iron Ore Types
Magnetite (FE3O4): This is a high-quality ore with about 70% iron. It's black and magnetic.
Haematite (FE2O3): This reddish ore has 60-70% iron.
Limonite: This yellowish ore contains 40-60% iron.
Siderite: This ore has less than 40% iron and many impurities, making it often not worth mining. Haematite and magnetite are the
most important iron ores in India.
About 79% haematite ore deposits are found in the Eastern Sector (Assam, Bihar, Chhattisgarh, Jharkhand, Odisha and Uttar Pradesh).
About 93% magnetite ore deposits occur in the Southern Sector (Karnataka, Andhra Pradesh, Goa, Kerala and Tamil Nadu).
Karnataka contributes around 70% of India's magnetite deposits.
