Concept: Definition of a Mineral

In geographical and geological terms, what exactly defines a 'Mineral'?

DEFINITION

Defining a Mineral

Nature: It is a naturally occurring substance of organic or inorganic origin.
Structure: It possesses a highly definite chemical composition and distinct physical properties.
Occurrence: Minerals are not distributed randomly; they are usually found associated with specific, ancient rock systems (e.g., the crystalline rocks of the Peninsular plateau in India).

Taxonomy: Classification of Minerals

How are minerals broadly classified based on their metallic content and composition?

CONCEPT

Mineral Classification Tree

Metallic Minerals: Contain extractable metal content.
- Ferrous: Contain Iron (e.g., Iron ore, Manganese). These provide a strong base for metallurgical industries.
- Non-Ferrous: Do not contain Iron (e.g., Copper, Bauxite, Gold).
Non-Metallic Minerals: Do not contain extractable metal (e.g., Mica, Limestone, Graphite).
- Note: Fossil fuels (Coal, Petroleum) are also technically classified under non-metallic mineral resources (Fuel Minerals).

Metals have Iron (Ferrous) or No Iron (Non-Ferrous). Everything else is Non-Metallic.

Resource Dynamics: Characteristics of Minerals

What are the three fundamental, inherent characteristics (and challenges) of mineral resources?

CONCEPT

The Three Fundamental Characteristics

Uneven Distribution: Minerals are concentrated in specific geological belts and are not spread equally over geographical space.
Inverse Quality-Quantity Relationship: High-grade, excellent quality minerals occur in very small quantities, whereas low-grade minerals are highly abundant.
Exhaustibility: They take millions of years (geological ages) to form and cannot be replenished immediately once mined, making them strictly non-renewable.
