Minerals and resources form the foundation of a nation’s economic development. They provide raw materials for industries, energy generation, infrastructure development, and technological advancement. India is blessed with a diverse range of mineral resources, making mining one of the important sectors of the economy. Questions related to minerals, mineral belts, energy resources, and their distribution are frequently asked in NDA and CDS examinations.
NDA & CDS 2 2026 Exam GK – Geography – Mineral & Resources
What are Minerals?
A mineral is a naturally occurring inorganic substance with a definite chemical composition and physical properties. Minerals are extracted from the earth through mining and are used in various industries.
Characteristics of Minerals
- Naturally occurring substances.
- Possess a specific chemical composition.
- Have definite physical properties.
- Found in rocks and the earth’s crust.
- Non-renewable in nature as their formation takes millions of years.
Classification of Minerals
Minerals are broadly classified into two categories:
1. Metallic Minerals
These minerals contain metals and can be processed to obtain useful metals.
Ferrous Minerals
Ferrous minerals contain iron and are essential for the metallurgical industry.
Examples:
- Iron Ore
- Manganese
- Chromite
- Nickel
Non-Ferrous Minerals
These minerals do not contain iron.
Examples:
- Copper
- Bauxite (Aluminium Ore)
- Lead
- Zinc
- Gold
- Silver
2. Non-Metallic Minerals
These minerals do not contain metals and are used in various industries.
Examples:
- Mica
- Limestone
- Gypsum
- Dolomite
- Phosphorite
