Ilmenite and rutile, abundantly available in certain coastal tracts of India, are rich sources of which one of the following?

Result
Your answer: —  ·  Correct: D
Explanation

Ilmenite and rutile are Ti-oxide minerals (titanium-oxide minerals)[1], making them rich sources of titanium. Coastal sands that are rich in ilmenite and rutile are commonly associated with a hinterland composed of high-grade metamorphic rocks[2], which explains their abundant availability in certain coastal tracts of India. These minerals are specifically valued for their titanium content and are classified as heavy minerals used in titanium extraction. India has significant reserves of these minerals along its coastal areas, particularly in states like Kerala, Tamil Nadu, and Odisha. The other options—aluminium, copper, and iron—while important industrial metals, are not the primary elements extracted from ilmenite and rutile. Therefore, option D (Titanium) is the correct answer.

This is a classic Economic Geography question derived from the 'Beach Sand Minerals' (BSM) complex. While standard NCERTs focus heavily on Monazite (Thorium), Ilmenite is its constant geological companion. If you study India's strategic minerals or the India Year Book (IYB) chapter on Industry/Resources, this is a direct hit.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Which chemical element is extracted from ilmenite and rutile, minerals abundantly found in certain coastal tracts of India?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Igneous rocks considered as probable sources of heavy minerals are particularly those enriched in Ti-oxide minerals, such as ilmenite and rutile (Force, 1991)."
Why this source?
  • Explicitly identifies ilmenite and rutile as titanium-bearing oxide minerals (Ti-oxide).
  • Directly ties ilmenite and rutile to titanium mineralogy, implying they are sources of titanium.
Web source
Presence: 5/5
"partitioning of titanium between silicate and oxide phases also depends on variables of rock composition... Coastal sands that are rich in ilmenite and rutile are commonly associ­ ated with a hinterland composed of high-grade metamorphic rocks."
Why this source?
  • Discusses titanium in the same context as ilmenite and rutile in coastal sands.
  • States that coastal sands rich in ilmenite and rutile are associated with titanium-bearing source rocks, linking these minerals to titanium.
Web source
Presence: 3/5
"The products from this stage can include HM, zircon, rutile, ilmenite or other concentrates."
Why this source?
  • Lists rutile and ilmenite among products/concentrates in the context of titanium mineral processing.
  • Shows these minerals occur in the concentrated heavy-mineral products associated with titanium minerals.

Why relevant

Lists ilmenite as a mineral found in coastal/southern belts and also names 'titanium' among elements in the continental shelf/seabed.

How to extend

A student can combine this with the common-knowledge fact that ilmenite/rutile are titanium-bearing minerals to suspect titanium is the element extracted.

Strength: 4/5
“The earth's crust is the major source of metals. Seawater also contains some soluble salts such as sodium chloride, magnesium chloride, etc. The elements or compounds, which occur naturally in the earth's crust, are known as minerals. At some places, minerals contain a very high percentage of a particular metal and the metal can be profitably extracted from it. These minerals are called ores.”
Why relevant

Explains that some minerals (ores) contain a very high percentage of a particular metal and that such metals can be profitably extracted.

How to extend

Use this rule to infer that if ilmenite/rutile are rich in a metal, that metal (from coastal deposits) would be the target of extraction.

Strength: 3/5
“Nuclear energy has emerged as a viable source in recent times. Important minerals used for the generation of nuclear energy are uranium and thorium. Uranium deposits occur in the Dharwar rocks. Geographically, uranium ores are known to occur in several locations along the Singbhum Copper belt. It is also found in Udaipur, Alwar and Jhunjhunu districts of Rajasthan, Durg district of Chhattisgarh, Bhandara district of Maharashtra and Kullu district of Himachal Pradesh. Thorium is mainly obtained from monazite and ilmenite in the beach sands along the coast of Kerala and Tamil Nadu. World's richest monazite deposits occur in Palakkad and Kollam districts of Kerala, near Vishakhapatnam in Andhra Pradesh and Mahanadi river delta in Odisha.”
Why relevant

States that thorium is obtained from monazite and ilmenite in beach sands, showing ilmenite occurs in coastal sands and is a source of extractable elements.

How to extend

Combine this pattern (beach sands → extractable elements from minerals like ilmenite) with the outside fact that ilmenite/rutile bear titanium to focus on titanium extraction as plausible.

“Thorium is derived from monazite. It is produced in Kerala, Jharkhand, Bihar, Tamil Nadu, and Rajasthan. In addition to uranium and thorium, beryllium and lithium are also the atomic minerals found mainly in Jharkhand, Madhya Pradesh, and Rajasthan. Salt is used mainly in chemical industry. Common salt (sodium chloride) is used as a food item. Salt is obtained from sea water, brine springs and salt pans in lakes. The main producers of salt are Gujarat, Maharashtra, Tamil Nadu, and Rajasthan. Gujarat coast accounts for about 50% of the total salt production of India. Sambhar lake of Rajasthan contributes about 10% of the total salt production of the country.”
Why relevant

Notes thorium is derived from monazite and that coastal/peninsular sands contain monazite and ilmenite, indicating coastal sands as sources of atomic/metallic elements.

How to extend

A student can generalize that coastal mineral sands (monazite, ilmenite, rutile) are mined for specific elements and therefore look up which element is associated with ilmenite/rutile (titanium).

Strength: 2/5
“A mineral is an aggregate of two or more than two elements. A mineral has a definite chemical composition, atomic structure and is formed by inorganic processes. In economic geography, the term mineral is used for any naturally occurring material that is mined and is of economic value. Minerals generally occur in the earth's crust in the form of ore. It is extracted, processed, and utilised for the economic benefits of society. The availability and per capita consumption of minerals is taken as an important indicator to assess the economic development of a country. India is fairly rich in mineral resources but their distribution is highly uneven.”
Why relevant

Defines minerals and ores and explains that minerals are mined and processed for economic use, framing why identifying the metal in ilmenite/rutile matters.

How to extend

Use this definition plus basic external chemistry/geology to check which metal is present in ilmenite/rutile and thus extracted from coastal tracts.
