Electrochemical behaviour and surface analysis of ...

It has been suggested that as a polysulfide passive layer thickens on a chalcopyrite surface, the separation of charge between the bulk mineral and solution grows wider and so the capacitance decreases (Nicol, 2017c). This behaviour of chalcopyrite in acid media was said to be similar to a thickening oxide layer on a metal.

Bornite is an important copper ore mineral. It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite. As a mineral specimen, bornite is usually lacking. Good crystals are rare and thus bornite is commonly known as simply a massive mineral ore. Also called "peacock ore".
