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.

Copper: The mineralogy of Copper - Mines, Minerals and More

Most widespread minerals containing Copper; This list of minerals containing Copper is built from the mindat locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Copper mineral species.

Sulfide Ores - an overview | ScienceDirect Topics

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu .
