A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic 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. The most common metal ores are oxides and sulfides. Sulfides are the oldest ores, formed in the Earth's history when there was a lot of ...
