Question

Distinguish between- three differences
a) Metallic and Non-metallic minerals.
b)Ferrous and Non-Ferrous Minerals

Answer 1

Metals are ductile and can be drawn into wires whereas non-metals are non-ductile and can't be drawn into wires. Metals are sonorous and used in ringing bells whereas non-metals are non-sonorous and cannot be used in ringing bells. Metals are good conductors of heat and electricity while non-metals are poor conductors.

Ferrous metals contain iron while non-ferrous metals do not.Non-ferrous metals have been used for much longer than ferrous metals. In 5000 BCE, the discovery of copper marked the end of the stone age. Later the invention of bronze, a non-ferrous alloy of tin and copper, began the Bronze Age. The use of ferrous metals began in earnest around 1200 BCE with the advent of the Iron Age. Since then, humanity has designated uses for both metal types based on their strengths and weaknesses.
