Showing 1–10 of 51 questions
Assertion (A) and the other labelled as Reason (R):
Assertion (A): The Peninsular plateau region of India holds the bulk of the country’s metallic mineral reserves.
Reason (R): The Peninsular plateau is primarily composed of ancient crystalline, igneous, and metamorphic rocks which are highly mineralised.
Select the correct answer from the codes given below:
Explanation
The Peninsular plateau serves as the storehouse of India’s metallic mineral wealth because it consists of ancient rock formations that underwent extensive tectonic and volcanic activity. These geological processes facilitated the concentration of minerals like iron and manganese within the crust. Therefore, the specific rock composition explains why the majority of the country’s mineral reserves are located here.Explanation
Magnetite is a very high-quality iron ore, typically possessing a distinctive dark grey to black colour. It contains a high iron content of up to seventy percent, making it extremely valuable for industrial use. Furthermore, it exhibits superior magnetic properties, which are particularly beneficial for applications in the electrical and electronic industries during the manufacturing of various components.I. Jharkhand and Odisha form a major contiguous iron ore belt.
II. Bailadila mines in Chhattisgarh are renowned for producing high-grade hematite ore.
III. Kudremukh deposits in Karnataka are exclusively mined for domestic consumption.
Which of the above statements is/are correct?
Explanation
The iron ore belt spanning Jharkhand and Odisha provides a significant portion of India’s total output. Specifically, the Bailadila mines in Chhattisgarh are famous for producing high-grade hematite ore, essential for steelmaking. However, the Kudremukh deposits in Karnataka operate primarily as export-oriented units, where iron ore is transported in slurry form via a pipeline to the coast.Explanation
Odisha is a leading producer of iron ore in India, with its high-grade hematite deposits concentrated in specific districts. The Kendujhar and Mayurbhanj districts are particularly prominent, featuring major mines like Badampahar and Gorumahisani. The Sundargarh district also contributes significantly to the state’s total output, supporting the raw material requirements of various domestic steel plants and international export markets.| Iron Ore Mine | State |
|---|---|
| A. Bailadila | i. Karnataka |
| B. Noamundi | ii. Odisha |
| C. Kudremukh | iii. Chhattisgarh |
| D. Badampahar | iv. Jharkhand |
Explanation
India’s iron ore mines are strategically located across diverse geological regions. The Bailadila mines are situated in Chhattisgarh, while the Noamundi mine is a major source of iron ore in Jharkhand. Kudremukh is located in the Western Ghats of Karnataka, and Badampahar is found in Odisha. These mines are integral to the industrial supply chains of their respective regions.Statement I: The Singhbhum district is famous exclusively for iron ore mining and lacks other metallic minerals.
Statement II: Singhbhum forms a part of the rich mineral belt extending across Jharkhand and Odisha.
Select the correct option:
Explanation
The Singhbhum district of Jharkhand is a highly mineralised zone and is not limited exclusively to iron ore extraction. It is also a significant producer of other metallic minerals, most notably copper. This district forms an integral part of the rich mineral belt that extends across the border into Odisha, making it one of the most productive mining regions.I. Siderite
II. Magnetite
III. Limonite
IV. Hematite
Select the correct order using the options below:
Explanation
Magnetite has the highest iron content, followed by hematite, then limonite and siderite. The order is II, IV, III, I.Explanation
Bailadila, Kudremukh, and Singhbhum are all major hubs for iron ore mining in India, contributing significantly to the steel industry and exports. In contrast, Khetri is primarily famous for its copper deposits and long-standing history of copper extraction. Therefore, it stands out from the other locations, which are predominantly associated with the production and processing of iron ore.Explanation
Madhya Pradesh is a leading state in the production of manganese ore in India. The Balaghat mines in this state are particularly renowned, contributing a significant percentage of the country’s total manganese output. Manganese is an essential raw material used in the iron and steel industry, and these mines play a crucial role in meeting domestic and international industrial demands.Answer key for these questions

Key facts from Minerals of India: Metallic and Non-Metallic
- Major metallic minerals are linked with ancient crystalline and metamorphic rocks; magnetite is the highest-grade iron ore.
- The Khetri copper complex in Jhunjhunu is one of the oldest in India; the Malanjkhand copper deposits are in Madhya Pradesh.
- The Zawar mines in Rajasthan are known for lead and zinc.
- Madhya Pradesh is the largest producer of manganese ore; the Sukinda Valley holds over 95 per cent of India’s chromite.
- Limestone is a weight-losing, bulky raw material, so cement plants sit near quarries.
- Rock phosphate is mined at Jhamarkotra in Udaipur; gypsum is used to reclaim alkaline and saline soils; the Barmer basin and the Krishna-Godavari Basin are important oil and gas areas.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Minerals of India: Metallic and Non-Metallic?
This page has 51 practice MCQs on Minerals of India: Metallic and Non-Metallic (Indian Geography). Each has the correct answer, and most have an explanation.
Which iron ore has the highest iron content?
Magnetite, with the highest iron content, followed by hematite, limonite and siderite. India has large deposits of hematite and magnetite, mostly in Odisha, Jharkhand, Chhattisgarh and Karnataka, and Indian ore is exported as well as used in domestic steel plants.
Where is the Sukinda Valley and what is it known for?
The Sukinda Valley is in Odisha and holds over 95 per cent of India’s chromite reserves. Chromite is used to make stainless steel and other alloys, and Odisha is by far the largest chromite producer.
Why are cement plants built near limestone quarries?
Because limestone is a weight-losing, bulky raw material. Making cement removes much of its weight, so it costs less to carry the cement to the market than to carry the limestone to a distant plant.
