Metal Ore
What is Metal Ore?
A rock containing enough of a metal compound to make extraction of the metal worthwhile. Most metals occur combined with oxygen or other elements rather than as the element itself, and how tightly the metal holds on to that combination is set by its position in the reactivity series.
This definition is part of the Metals chapter in Cambridge IGCSE Chemistry.
