Question

Distinguish between metallic and non-metallic minerals with examples.

Hint:

To distinguish between metallic and non-metallic minerals, focus on their properties like conductivity and their industrial uses. Metallic minerals contain metals and are essential for the production of machinery, while non-metallic minerals are used in construction and chemical industries.

Answer 1

Minerals, valuable naturally occurring substances, are categorized into metallic and non-metallic types.
1. Metallic Minerals:
- Characterized by the presence of metals in their unprocessed form. They typically exhibit shininess, good thermal and electrical conductivity, and high melting points.
- Extracted via mining and subsequent refining. Industrial applications include manufacturing machinery, tools, and electrical components.
- Illustrative examples: Iron ore (for steel), Copper ore (for copper), Bauxite (for aluminum), Gold and silver (for jewelry and electronics).
2. Non-Metallic Minerals:
- Lack metallic content and are generally dull and poor electrical conductors.
- Primarily utilized in construction, manufacturing, and as feedstock for chemical industries.
- Often used directly in their natural state with minimal processing.
- Illustrative examples: Limestone (for cement), Marble (for sculptures and buildings), Salt (for food preservation and industry), Clay (for pottery and bricks).
