Minerals and Ores Questions

Multiple choice

Which of the following are feldspar minerals? (A) Celsian (B) Crystobalite (C) Heulandite (D) Anorthite

  1. (A) and (D)

  2. (C) and (D)

  3. (A), (B) and (C)

  4. (C) and (B)

  5. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This option is correct because the felspars are most important rock minerals in which Ba++, K+, Ca++, are linked with three dimensional framework of the SiO4 and AlO4 in tetrahedron. Celsian and anorthite are best known examples of  felspar. (Celsian = BaAl2Si2O8, and Anorthite = CaAl2Si2O8)

Multiple choice

  4. (A) 1 (B) 2 (C) 3 (D) 4
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Brazil is the world's largest bauxite producer, South Africa dominates gold production, USA is a major copper producer, and Malaysia historically led in tin mining. The matching in Option A correctly pairs each mineral with its principal producer. This tests knowledge of global mineral distribution patterns.

Multiple choice

India is very poorly endowed with a few essential minerals and therefore, depends on other countries for the supply of all of the following minerals, except

  1. antimony

  2. cobalt

  3. thorium

  4. zinc
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

India is rich in thorium deposits found in monazite sands along Kerala's coast. India imports antimony, cobalt, and zinc due to scarce domestic reserves. Thorium is the exception because India has abundant reserves, making it self-sufficient.

Multiple choice

Which of the following minerals occurs abundantly in the earth’s crust?

  1. Silica

  2. Iron

  3. Manganese

  4. Aluminium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silica (silicon dioxide) is the most abundant mineral in Earth's crust, making up about 59% of the crust's weight. It's found in quartz and various silicate minerals. While iron, manganese, and aluminum are common, silica is by far the most abundant element in the crust.

Multiple choice

Neyveli is famous for

  1. crude oil

  2. lignite coal

  3. salt production

  4. iron ore
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Neyveli in Tamil Nadu is famous for its lignite (brown coal) mines and thermal power station. It's one of India's largest lignite mining operations. Neyveli is not associated with crude oil, salt production, or iron ore mining - lignite is its signature resource.

Multiple choice

Which mineral is mainly used in the asbestos industry?

  1. Pyroxene

  2. Amphibole

  3. Quartz

  4. Feldspar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Asbestos industry primarily uses amphibole varieties of asbestos minerals (like crocidolite and amosite) for manufacturing asbestos products. Asbestos is a fibrous mineral, and amphibole-type asbestos is widely used in industrial applications due to its heat resistance and durability. Pyroxene, Quartz, and Feldspar are common minerals but not used in asbestos production.
