Metallic minerals are primarily composed of metals like iron, copper, and gold, essential for industrial applications such as construction, electronics, and manufacturing. On the other hand, industrial minerals include non-metallic resources like limestone, gypsum, and quartz, crucial for diverse sectors like construction, agriculture, and ceramics.
Key Takeaways
- Metallic minerals contain metals in their raw form, such as iron, copper, and gold, which can be extracted and refined for various uses.
- Industrial minerals are non-metallic minerals used in various industries for construction, manufacturing, and agriculture, including limestone, gypsum, and talc.
- The primary distinction between the two is their composition and usage: metallic minerals contain metals. They are used in metal production, while industrial minerals are non-metallic and have various industrial applications.
Metallic vs Industrial Minerals
The difference between metallic and industrial minerals is that in metallic minerals metals occur in the raw form, which can be further extracted for functional purposes. In contrast, industrial or non-metallic minerals are substances that lack the presence of metals in them.
Metallic minerals are minerals that contain one or more than one metals. These occur in rare and naturally occurring concentrations as mineral deposits.
Industrial minerals, called non-metallic substances, do not contain metals and are used in various industries to produce multiple products.
Metallic minerals are the excellent conductor of heat and electricity due to the presence of metals, whereas Industrial minerals are the poor conductor of heat and electricity.
Metallic minerals can be further classified into two more categories that are:
- Ferrous minerals- the metallic minerals which contain iron are called ferrous metallic minerals. Ex. Iron ore, manganese, nickel, etc.
- Non-ferrous minerals- the metallic minerals not containing iron are called non-ferrous minerals—Ex—aluminium, lead, copper, etc.
