Minerals: A mineral is a solid, naturally occurring inorganic substance having a well-defined crystalline structure and chemical composition. The amorphous and biogenic substances are still not considered minerals though a debate is going in this aspect. Minerals can be classified as metallic and non-metallic minerals.
Metallic minerals are shiny, ductile (can be deformed without losing toughness), malleable (can be pressed into shape without breaking) . They are generally obtained from igneous rocks. They can be melted to obtain metals. They are good conductors of heat and electricity. Metallic minerals can be classified as ferrous and non-ferrous minerals. Ferrous minerals contain iron and non-ferrous minerals do not contain iron.
Non-metallic minerals are not shiny, not ductile and non-malleable. They are generally obtained from sedimentary rocks. They do not give any product on melting. They are bad conductors of heat and electricity.
