Get PriceIt 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.
