Copper is a metallic mineral.
Option: D
Explanation:
- Metallic minerals are the ones that are sources of metals. They are usually abiotic.
- They are not formed from plant or animal remains.
- A metal is an element which is hard, lustrous, sonorous, and ductile and has a very high melting point. Copper has all these properties.
- It has a very ‘high melting point’ at 1085°C. Hence it is a metallic mineral.
- Coal, limestone, mica on the other hand are relatively soft, ‘non-lustrous’, non-sonorous and have relatively ‘low melting points’.
- Hence they are all non-metallic minerals.
