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 are naturally occurring substances that are extracted for their economic value. They are broadly classified into two categories: metallic minerals and non-metallic minerals. Here’s a detailed distinction between the two:
1. Metallic Minerals:
- Metallic minerals contain metals in their raw form. These minerals are generally shiny, good conductors of heat and electricity, and have high melting points.
- They are usually extracted by mining and refining to extract the metal. Metallic minerals are used for various industrial purposes, including manufacturing machinery, tools, and electrical components.
- Examples of metallic minerals include: - Iron ore (used to make steel) - Copper ore (used to produce copper) - Bauxite (used to produce aluminum) - Gold and silver (used in jewelry and electronics)
2. Non-Metallic Minerals:
- Non-metallic minerals do not contain metals and are generally not shiny or good conductors of electricity.
- These minerals are primarily used for industrial purposes like construction, manufacturing, and as raw materials in chemical industries.
- Non-metallic minerals are used directly in their natural state and require minimal processing.
- Examples of non-metallic minerals include: - Limestone (used in cement production) - Marble (used for sculptures and building material) - Salt (used for food preservation and industrial purposes) - Clay (used in pottery and brick making)
