One item to consider is that copper is electrolytically purified by psssing current between a thin cathode of pure copper and a thick cathode of impure copper. An electrical power supply drives the copper (in solution) from the anode (+) to the cathode (-), and less reactive metals precipitate while more reactive metals remain in solution.

Quick Question: Copper and Brass cause corrosion?

Sep 13, 2021There is no generic blend of corrosion inhibitors for all situations. Many additives use organophosphates. These work great for protecting iron and aluminum, but increase the rate of corrosion on copper and copper alloys (such as brass and bronze). Tolytriazole is excellent for protecting copper alloys, but isn't always included due to cost.
