State any one characteristic each of ferrous and non-ferrous minerals.

Metallic minerals are the sources of metals. Some examples of such minerals include iron ore, copper, gold etc. The characteristics of metallic minerals are as follows:

a. Ductile – It means that the metallic minerals can be drawn into wires and is flexible.

b. Malleable – It means the ability to be beaten into sheets.

c. Conductor of heat and electricity – The metallic minerals are good conductors of heat and electricity and has the capability to transmit it.

d. Sonorous – The metallic minerals are sonorous which means it has the capacity to produce ringing sound.

On the other hand, non-metallic minerals do not possess any of these properties. These usually include fossil fuels or inorganic minerals like mica, limestone etc.

Metallic minerals can be classified into ferrous and non-ferrous minerals. Ferrous minerals are those minerals that have some content of iron ore in its composition like manganese or iron while non-ferrous minerals have no iron content. The examples of non-ferrous minerals are copper and bauxite. The minerals have an inverse relationship with quality and quantity i.e. if the quality of minerals is good then its availability are less and vice versa. Minerals take a long time to develop and therefore should be used judiciously.
