Minerals are solid, naturally occurring inorganic substances that can be found in the earth’s crust. They are formed without the intervention of humans and have a definite chemical composition and crystal structure.
Metals are elementary substances, such as gold, silver and copper that are crystalline when solid and naturally occurring in minerals. They often have the characteristics of being good conductors of electricity and heat, of being shiny in appearance and of being malleable. The metals we see day-to-day are produced through the conversion of metallic ores to a final form. This, in the majority of cases, requires the use of chemicals and special technologies[1].
