Minerals Are the Foundation of Societies
Nearly every man-made thing around you is made from minerals. Can you name something man-made that does not contain minerals? Roads, buildings, and computers—even food—contain minerals. There are minererals in the display you're viewing!
The majority of the raw material used in building your home was furnished by the mining industry.
