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.
