Geochemistry of Copper
Goldschmidt classification:Chalcophile
Cu2+ was one of the ions least depleted from the mantle in the formation of the crust.
Cu2+ is concentrated in deep-sea ferromanganese nodules relative to seawater.
Cu2+ solute can be a limiting nutrient in the growth of bacteria.
Cu2+ solute is a micronutrient on land.
Cu2+ is essential to nutrition of at least some vertebrates ('essential minerals').

Element association of Copper in the Mineral World
This table compares the known valid mineral species listed listed with Copper and the other elements listed based on the official IMA formula. Note that unlike other sections on this page this includes non-essential elements.

The first data column contains the total number of minerals listed with Copper and the element listed for that row.

The second data column lists this number as a percentage of all minerals listed with Copper.

The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row.

Most widespread minerals containing Copper
This list of minerals containing Copper is built from the mindat.org 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. It is more useful when comparing rare species rather than common species.
