Copper extraction Wikipedia

Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.

copper oxide ore pyrometallurgy

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper.
