Minerals are typically classified into two broad categories:
metallic minerals and non-metallic minerals.
1. Metallic minerals contain metals in their composition and can be used to extract metals for industrial purposes. Examples of metallic minerals include iron ore, copper, manganese, aluminum, gold, etc. These minerals are important for the production of various metals used in manufacturing, construction, and technology.
2. Non-metallic minerals do not contain metals and are usually used for other purposes like construction, fuel, and chemical production. Examples include limestone, coal, and sulphur.
Among the given options:
- Limestone (A) is a non-metallic mineral used primarily in construction and manufacturing, especially in the production of cement.
- Sulphur (B) is a non-metallic mineral, mainly used in the chemical industry.
- Manganese (C), however, is a metallic mineral. It is used primarily in steel production and is essential for the manufacturing of alloys.
- Coal (D) is also a non-metallic mineral used as a fossil fuel.
Thus, the correct answer is Manganese (C), a metallic mineral.
