Mineral A mineral is a naturally occurring inorganic element of compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Minerals may be metallic, like gold, or nonmetallic, such as talc. Coal, oil, and natural gas are generally considered to be “energy minerals.
Around 99% of the minerals in the Earth's crust are made up of eight elements including oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
