4. Some Terms – Lets Have a Look Minerals: A solid element or compound which occurs naturally in the Earth's crust is called a mineral. Ore: A mineral from which metals can be extracted profitably is called a metal ore. Profitable extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.
