Copper: The mineral native Copper information and pictures

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.
